fix(ai): rename providerMetadata -> metadata in makeToolCall test helper by AlemTuzlak · Pull Request #546 · TanStack/ai

AlemTuzlak · 2026-05-11T14:16:57Z

Summary

Fixes pnpm test:ci on main, which has been failing on @tanstack/ai:test:types since fix(ai-gemini): read/write thoughtSignature at Part level for Gemini 3.x #459 was merged.
fix(ai-gemini): read/write thoughtSignature at Part level for Gemini 3.x #459 renamed ToolCall.providerMetadata → ToolCall<TMetadata>.metadata across src/, but missed the makeToolCall test helper in packages/typescript/ai/tests/middlewares/fake-otel.ts. tsc now errors with TS2339: Property 'providerMetadata' does not exist, which is what's blocking the Release workflow's Run Tests step and preventing the changesets release PR from being (re)created.
Test-only change: 2-line rename in the helper. No published surface affected, no changeset needed.

Root cause

In #459 (87f305c), ToolCall.providerMetadata: Record<string, unknown> became ToolCall<TMetadata>.metadata?: TMetadata everywhere except the makeToolCall test helper, whose conditional spread still references the old field name. The helper is typed against the current ToolCall, so tsc rejects it.

Test plan

pnpm --filter @tanstack/ai test:types passes locally
pnpm --filter @tanstack/ai test:lib passes locally (751 tests)
pnpm --filter @tanstack/ai test:eslint clean
Release workflow on main goes green after merge, allowing the changesets release PR to be created

Summary by CodeRabbit

Chores
- Updated internal test infrastructure to refine mock data structure handling.

Follow-up to #459, which renamed ToolCall.providerMetadata to ToolCall<TMetadata>.metadata across src/ but missed this test helper. tsc fails on main with TS2339 on tests/middlewares/fake-otel.ts, breaking pnpm test:ci and blocking the changesets release PR from being created.

Poem

🐰 A tiny tweak in the test mock's nest,
From providerMetadata to metadata blessed,
The helper now spreads the correct property name,
Test utilities hop forward, all staying the same! 🌟
