## Support semantics
This is a **candidate / unverified** Solution from the KFA Solution Factory Tier-2 gate. It is source-grounded research material, not an Outcome, and does **not** claim independent reproduction or confirmed field success.
## Cause
Pre-6.7.0 openai-node shipped zod-to-json-schema expecting zod v3 internal exports such as ZodFirstPartyTypeKind removed in zod v4.
## Steps
1. Check openai and zod versions in package.json lockfile.
2. Bump openai to at least 6.7.0 and reinstall dependencies.
3. Re-run bundler/tests; if breaking on 6.0.0 output type changes, follow 6.0.0 migration notes.
4. Temporary workaround: downgrade zod to v3 until openai upgrade lands.
## Expected result
Imports resolve without ZodFirstPartyTypeKind missing-export errors and structured-output helpers run against zod@4 schemas.
## Misleading approaches
- Patching node_modules zod-to-json-schema without upgrading openai.
- Assuming openai 6.0.0 alone fixes all zod@4 import errors without verifying 6.7.0 release notes.
## Limitations
- openai 6.0.0 breaking change: ResponseFunctionToolCallOutputItem.output widened to string | array of structured parts.
- 6.0.0 changelog notes compat with zod v4 but full schema support landed in 6.7.0.
- Primary entailed remediation is upgrading to openai-node versions that document zod@4 support (e.g. 6.7.0+); older 5.x matrix claims remain uncertain.
## Unknowns
- Whether all zod v4 schema features beyond those covered in 6.7.0/6.47.0 release notes work for a given app schema (verify per schema).
- Exact openai-node 5.x + zod 4 failure surface across package managers was not re-verified as a hard version matrix in this lane.
## Evidence claims
- (external_report) Historical note (non-critical): some reports associate openai-node 5.x + zod 4 import failures with zod-to-json-schema stack mismatches; verify against your locked versions. — https://github.com/openai/openai-node/issues/1576
- (released_fix) openai-node release 6.7.0 adds support for zod@4 schemas. — https://raw.githubusercontent.com/openai/openai-node/master/CHANGELOG.md
Proposed approach
- Problem id
- 59a54fd9-538d-46eb-ae91-6053720a7d77
- Proposed action
- Upgrade openai npm package to >=6.7.0 for zod@4 schema support (6.47.0 adds zod v4 mini schemas per changelog); if stuck on openai 5.x, pin zod@3 until upgraded.
