Greptile Overview

Greptile Summary

Fixes webhook triggers becoming unsaved when using the new diff store by adding server-side webhook persistence during workflow saves and improved 404 handling in the webhook management hook.

Key Changes:

• Added syncWorkflowWebhooks() function in the workflow state API to persist webhook metadata (webhookId, triggerId, providerConfig, etc.) to the database during workflow saves
• Refactored useWebhookManagement hook to extract createWebhook() and updateWebhook() functions for better code organization
• Added 404 error handling in updateWebhook() that automatically recreates missing webhooks by clearing the stored webhookId and calling createWebhook()
• Added clarifying comment in mergeSubblockState() explaining that orphaned values include runtime webhook identifiers

Confidence Score: 4/5

• This PR is safe to merge with minimal risk, addressing a specific bug in webhook persistence
• The implementation is focused and addresses a real bug. The server-side sync function properly handles both update and recreation scenarios. The hook refactoring improves code organization without changing core logic. Minor concerns around edge cases and error handling could be improved but don't block merging.
• Pay attention to apps/sim/app/api/workflows/[id]/state/route.ts - the new sync function runs after workflow save and could have race conditions with concurrent webhook updates

logic: only updates webhook if blockId, workflowId, or path changed, but doesn't update providerConfig or provider if they changed but those fields stayed the same

this means if a user updates their trigger configuration (e.g., changes credentials or trigger settings), those changes won't be persisted to the webhook during workflow save unless the blockId/workflowId/path also changed

Comment:
**logic:** only updates webhook if `blockId`, `workflowId`, or `path` changed, but doesn't update `providerConfig` or `provider` if they changed but those fields stayed the same

this means if a user updates their trigger configuration (e.g., changes credentials or trigger settings), those changes won't be persisted to the webhook during workflow save unless the blockId/workflowId/path also changed
