@ai-sdk/workflow: package.json points to files that aren't published

[isimisi]

@ai-sdk/workflow@1.0.17 publishes only dist/index.mjs and dist/index.d.mts, but package.json points elsewhere:

"main": "./dist/index.js",
"exports": { ".": { "types": "./dist/index.d.ts", "import": "./dist/index.mjs", "require": "./dist/index.js" } }

dist/index.js and dist/index.d.ts aren't in the tarball, so require('@ai-sdk/workflow') throws MODULE_NOT_FOUND. import() resolves fine via the import condition.

Identify issue type

Identified as Bug
Confidence: High

Rationale

The issue reports an existing package publishing/entrypoint mismatch that causes a runtime module resolution failure for require users.

Evidence

• @ai-sdk/workflow@1.0.17 package.json declares CommonJS entry points ./dist/index.js and ./dist/index.d.ts.
• The published tarball only contains dist/index.mjs and dist/index.d.mts, so the declared require/types files are missing.
• Reporter states require('@ai-sdk/workflow') throws MODULE_NOT_FOUND while import resolves via the import condition.

Bug Reproduction

Bug was reproduced.

Branch: main
PR: successful reproduction pull request

Details

• Classified issue @ai-sdk/workflow: package.json points to files that aren't published #16925 as general library/package publishing behavior, not provider-specific behavior.
• Added examples/ai-functions/src/reproduction/workflow-require-entrypoint.ts to pack @ai-sdk/workflow@1.0.17, inspect the published tarball, and require it from a temporary node_modules install.
• The published tarball contains dist/index.mjs, dist/index.d.mts, and dist/index.mjs.map, while package.json declares ./dist/index.js for main and exports["."].require, plus ./dist/index.d.ts for types.
• The reproduction script observes require("@ai-sdk/workflow") failing with MODULE_NOT_FOUND for missing dist/index.js; this matches the expected issue behavior for CommonJS consumers while the import target exists.

Bug Reproduction

Bug was reproduced.

Branch: main
PR: successful reproduction pull request

Details

• Classified issue @ai-sdk/workflow: package.json points to files that aren't published #16925 as a general package publishing/Node resolution bug affecting CommonJS consumers of @ai-sdk/workflow.
• Added runnable reproduction artifact at examples/ai-functions/src/reproduction/workflow-require-entrypoint.ts.
• Expected correct behavior is for require('@ai-sdk/workflow') to resolve to a published package entrypoint declared by exports["."].require; observed MODULE_NOT_FOUND because that entrypoint points at missing dist/index.js.
• The @ai-sdk/workflow@1.0.17 tarball contains dist/index.mjs and dist/index.d.mts, but not the declared dist/index.js or dist/index.d.ts files.
• The reproduction also confirms ESM resolution succeeds through dist/index.mjs, matching the reported import-vs-require mismatch.

Bugfix

Created bugfix and updated PR: #16992

Summary

Marked @ai-sdk/workflow as an ESM package and aligned main/types/exports to the generated dist/index.js and dist/index.d.ts files, removing stale module and require targets.

Testing

Added a workflow package.json entrypoint regression test and updated the reproduction example to pack the local package and assert import, require, and type entrypoints.
