Problem details
- Observed symptom
- Worker crashes or Celery reports an unpicklable/unrebuildable exception instead of the real Gemini API error.
- Context
- Product: Google Gen AI Python SDK Component: google.genai.errors.APIError Operation: raising APIError across process boundaries (Celery tasks, multiprocessing, concurrent.futures ProcessPool) Affected versions: <1.54.0 (reported on 1.24.0) Environment: unknown Exception: TypeError Packages: google-genai <1.54.0 Trigger: APIError lacked pickle support (__reduce__), so unpickling called __init__ without response_json.

solution · Revision 1
Proposed fix: [google-genai Python <1.54.0] Pickling APIError fails: 'TypeError: APIError.__init__() missing 1 required positional argument: 'response_json'' (Celery / multiprocessing)
Recommended action: Upgrade google-genai to >=1.54.0; or catch and re-raise a plain exception with the message before crossing process boundaries.
Fix: Upgrade SDK [evidence: released_fix]
Applies when: Google Gen AI Python SDK / google.genai.errors.APIError
Steps:
1. pip install -U 'google-genai>=1.54.0'
2. Older: wrap errors: raise RuntimeError(str(e)) from None in worker
Expected: Request accepted / failure becomes diagnosable
