Failing test: switching away from a failed workflow and back leaves the Errors panel empty because app.clean() clears the execution error store and nothing restores it.
Run errors lived in one global bucket that app.clean() emptied on every graph load, so switching workflow tabs destroyed the failed run state of the outgoing workflow and nothing brought it back. Key the store's run errors by root graph id and let the active bucket follow the loaded root graph: clean() detaches, afterLoadNewGraph points the store at the incoming graph. Errors stay isolated per workflow and return with their workflow.
📝 WalkthroughWalkthroughChangesGraph-scoped execution errors
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change scopes execution errors by workflow, but current behavior can still reuse IDs across distinct tabs or create a new ID during temporary reloads, causing errors to leak between workflows or disappear. The persistence test also does not verify the real reopen path, so the PR is not merge-ready until these issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

SHOULD FIX: This key is still zeroUuid for workflows created by loadApiJson() and importA1111(): both clear and manually populate the root graph without calling LGraph.configure(). Those imports therefore share one error bucket, and the first later tab reload replaces the zero ID with a generated UUID, making the saved errors disappear again. Assign a stable non-zero workflow ID before selecting the bucket (or key by workflow identity), and cover an imported workflow in the regression test.

Fixed in ad4d328.
Confirmed: LGraph.clear() resets id to zeroUuid, and neither loadApiJson() nor importA1111() reaches _configureBase(), so the id stayed zero. afterLoadNewGraph() now mints an id for a zero-id root graph before selecting the bucket, and writes it back into workflowData — that object is rootGraph.serialize() at every call site and becomes changeTracker.activeState, so without the write-back the reload would still configure from a zero id and regenerate.
Regression test added in app.test.ts ("gives each imported workflow its own restorable run errors"): two imports through the no-configure() path get distinct non-zero ids, and reopening the first from the state it persisted restores its errors. Verified it fails on the previous commit.

SHOULD FIX: clearRunErrors() also reset isErrorOverlayOpen; setActiveGraph(null) leaves that global bit set. After switching away from an open error overlay, a destination workflow's cached missing-model/media warnings are restored with silent: true, but the stale bit makes the overlay visible anyway. Reset or scope the overlay-open state when detaching so silent tab restoration remains silent.

Fixed in 81126fb.
Confirmed the exact path you describe: openWorkflow() -> loadGraphData() -> clean()/afterLoadNewGraph(), then showPendingWarnings(undefined, { silent: !loadFromRemote && !options.force }). On a tab switch that is silent: true, but the restored missing-model/media candidates still push totalErrorCount > 0, and useErrorOverlayState.isVisible only needed the stale isErrorOverlayOpen to go true.
setActiveGraph() now clears isErrorOverlayOpen whenever the active graph changes, which restores the old clean() behaviour and keeps the flag scoped to the graph in front. It runs at the top of afterLoadNewGraph(), before showPendingWarnings() decides, so a non-silent load can still open the overlay.
Store test added ("closes the error overlay when the active graph changes"); verified it fails on the previous commit.

Please check the should fixes.
loadApiJson() and importA1111() populate the root graph in place and never call configure(), so it keeps the zero id that LGraph.clear() leaves behind. Every such import shared one bucket, and the first reload swapped the zero id for a generated one, losing the parked errors again. afterLoadNewGraph() now mints an id for a zero-id root graph before selecting the bucket, and writes it back into the state this load persists so the reload lands on the same key. Addresses #15361 (comment)
clean() used to call clearRunErrors(), which also reset isErrorOverlayOpen. setActiveGraph(null) left that global bit set, so a destination workflow whose cached missing-model/media warnings are restored with silent: true would still pop the overlay. setActiveGraph() now dismisses the overlay on every move, restoring the old clean() behaviour and keeping it scoped to the graph in front.

Reviewed at 81126fb. The headline fix holds up: run errors survive tab switches, the bucket-per-root-graph model matches the widgetValueStore/previewExposureStore precedent, and each of the three commits is load-bearing (reverting any one of them fails a test). Subgraph navigation, page reload, and the store's consumers all behave the same as before during the transient detached window.
Four items inline — the first is the one I'd fix before merge; the other three are a smaller code fix and two test gaps.
Two notes that don't need code changes in this PR:
-
The lifecycle clears at
executionStore.ts:457/:808and the post-await write atapp.ts:1746still target whichever bucket is currently active, so a background job's events can clear or patch the viewed tab's parked errors. Not a regression (those files are unchanged, and the old global store was wiped on every switch anyway), but it bounds the "starting a run in B leaves A's parked errors intact" claim to node errors outside those windows. Worth folding the clearing side into FE-1648's scope explicitly — routing only therecord*calls won't cover the two clear sites, andapp.ts:1746sits outsideexecutionStore, so it needs its own captured target the way line 1702 already capturesqueuedWorkflow. Related: since a mis-filed error now persists in the wrong graph's bucket instead of dying on the next switch, FE-1648 inherits a stickier symptom (including one spurious auto-queue pass, and auto-queue being suppressed on the innocent workflow that received the error). -
Nit: closing a saved workflow and reopening it in the same session re-attaches its old bucket, so stale badges resurface even if the failure was fixed in between (fresh API/A1111 imports re-mint and are unaffected). That's consistent with the parking design, but worth a sentence in the description. Also,
closeWorkflow()does haveactiveState.idin hand before delegating, so a close-time eviction hook looks more reachable than the description suggests.

Issue: not every clean() is followed by a load, and those paths now end permanently detached. Comfy.ClearWorkflow (useCoreCommands.ts:279) and the legacy Clear button (ui.ts:696) call clean() standalone, and a failed configure() returns from the catch in loadGraphData before afterLoadNewGraph runs. In all of those, activeGraphId stays null, so updateActiveRunErrors drops every subsequent validation/prompt/websocket error until some later load re-attaches. Clear → rebuild → Run reports nothing — and with the default Comfy.RightSidePanel.ShowErrorsTab setting the error dialog is suppressed and the overlay opens empty. Pre-PR, clean() cleared the globals but recording kept working.
Suggestion: have the standalone Clear paths re-attach (they still hold a root graph with a valid id), or make clean() clear the active bucket and only detach when a load is actually pending.
There was a problem hiding this comment.
Addressed in 3ba549a. clean() now gives a cleared root graph a stable non-zero ID and immediately reattaches the execution-error store. Errors produced after a standalone Clear—or after a load exits before afterLoadNewGraph()—are recorded again instead of being dropped. Added a regression test covering recording after clean().

Issue: minting only for the zero id leaves a collision for non-zero duplicates. _configureBase preserves any serialized non-zero id, and Save-As/Duplicate are the only flows that regenerate one — re-dropping the same saved/exported JSON while its first tab is inactive dedupes the path (file (2).json) but not the id, so two open tabs share one runErrorsByGraphId entry: the twin tab shows the other tab's run errors, and clearing via one destroys the other's. subgraphNavigationStore hit the same shape and keys by workflowPath:graphId (with a same-graph-id/different-workflow test); the same composite key would work here.
There was a problem hiding this comment.
Addressed in fc67551. Run-error buckets now use the composite workflow path + root graph ID key, matching the isolation shape used by subgraph navigation. Two open workflows with the same serialized graph ID no longer share or clear each other’s errors; the store test covers that collision directly.

Issue: this runs before the isSameActiveWorkflowLoad guard below, and every API/A1111 import re-mints (clean() resets the root id to zero), so the guard's activeState.id === workflowData.id comparison now always fails for a re-import of the same file — each re-import opens a name (2).json duplicate tab where the active tab used to be reused. Reordering alone wouldn't fix it (the minted id still reaches activeState.id through later serialization); since the write-back is what keeps the error key stable across reloads, the reuse guard needs to tolerate the import case instead. Note the existing afterLoadNewGraph service tests don't catch this because their app mock has no isGraphReady, so adoptRootGraphId early-returns there.

Suggestion: every test in this block records only node errors, so an implementation that parks nodeErrors but wipes executionError/promptError on each switch passes the whole suite (I checked this against the two targeted files and the store's consumer suites). Since the change migrates all three fields into the bucket, one test that records an execution error and a prompt error under graph A and asserts both come back after A→B→A would pin the other two thirds.

Suggestion: this feeds firstImport.id straight back in — the same object adoptRootGraphId mutated in place — and the mock change tracker's reset is inert, so the comment above overclaims: a regression that stops retaining the minted id across the real persistence boundary (createNewTemporary / ChangeTracker.reset) keeps this test green. Driving the real loadApiJson twice (as the tests around lines 836/949 already do) would exercise the filename → createNewTemporary branch the production imports actually take.
Nit: firstImport.id! — the file's idiom elsewhere is throw-narrowing.
There was a problem hiding this comment.
Addressed in 1dc34bd. The import isolation test now drives real loadApiJson() calls for two filenames through createNewTemporary and real ChangeTracker state, then reopens the first persisted import and verifies its errors return. The non-null assertion was replaced with throw-based narrowing.

Extract the zero-id minting rule into one shared helper.
Lines 2448-2450 duplicate the rule in adoptRootGraphId at src/platform/workflow/core/services/workflowService.ts Line 60. Both sites implement "if the root graph id is the zero UUID, mint a new one". If one site changes, the two layers can disagree about graph identity, and the error bucket key drifts. Move the rule into src/utils/uuid.ts (or a small graph-identity helper) and call it from both sites.
♻️ Proposed shared helper
Add to src/utils/uuid.ts:
import type { UUID } from '`@/utils/uuid`'
/** Returns the graph id, minting one when the graph still carries the zero id. */
export function ensureNonZeroGraphId(graph: { id: UUID }): UUID {
if (graph.id === zeroUuid) graph.id = createUuidv4()
return graph.id
}Then in src/scripts/app.ts:

this.rootGraph.clear()
- if (this.rootGraph.id === zeroUuid) {
- this.rootGraph.id = createUuidv4()

Add coverage for bucket pruning.
updateActiveRunErrors deletes the bucket when nodeErrors, executionError, and promptError all become null. No test exercises that branch. clearRunErrors uses a separate Map.delete path, so these tests do not reach it. Without coverage, a regression that leaves an all-null bucket behind stays invisible, and the map grows for every workflow that ever produced an error.
As per path instructions, .agents/checks/test-quality.md requires review coverage for "bucket pruning".

There was a problem hiding this comment.
The "Can duplicate workflow" e2e failure looks related to 04b4ce1: duplicating an unsaved (Copy) tab loads under the same filename, and duplicateWorkflow() signals "this is a distinct workflow" by minting a new id — but isTemporary now short-circuits the id comparison, so the guard reuses the active tab and the (Copy) (2) tab never gets created. The distinguishing signal might be whether workflowData.id was zero before adoptRootGraphId overwrote it (re-imports mint, duplicates supply their own id) — limiting the temporary reuse to the minted case would keep both paths working.


Run a workflow, have it fail with node errors, switch to another workflow tab, switch back — the red badges are gone, the Errors panel is empty and
totalErrorCountreads 0, while the graph is still in exactly the state that failed.ComfyApp.clean()runs on every graph load and calledexecutionErrorStore.clearRunErrors(), which nulled the store's single globallastNodeErrors/lastExecutionError/lastPromptError. Nothing restored them:ChangeTracker.restore()coversds,nodeOutputsand subgraph nav, andshowPendingWarnings()replays only missing node/model/media state. Every writer into the store is a websocket event or a queue-prompt response, so there is no reload path that repopulates them either.Run errors are keyed by root graph id now, following the same shape as
widgetValueStoreandpreviewExposureStore. The active bucket follows the loaded root graph:clean()detaches the store,afterLoadNewGraphpoints it at the incoming graph's id. NoChangeTrackerfield and no transient-state registration, so this does not prejudge #14941.Notes for review:
clearRunErrors()(queue-prompt) now drops only the active graph's bucket, so starting a run in workflow B leaves A's parked errors intact.afterLoadNewGraphmints a root graph id when it finds the zero id, and writes it back into the state the load persists.loadApiJson()andimportA1111()populate the root graph withoutconfigure(), so they would otherwise share the zero id's bucket and lose it on the first reload.setActiveGraph()dismisses the error overlay whenever the active graph changes, preserving theisErrorOverlayOpenreset thatclean()used to get fromclearRunErrors(). Without it a silent tab restore of cached missing-model/media warnings would pop the overlay.LGraph.clear(), which fires on every tab switch and would re-break this fix. Evicting properly needs a graph-id-aware close hook that does not exist yet.Errors from a background workflow's job are still recorded into whichever bucket is active and resolved against
app.rootGraph, so they can attach to the wrong nodes while two workflows are live. That is a separate defect with a separate fix (routing viaexecutionStore'sjobIdToWorkflow) and is filed as FE-1648 rather than bundled here.
