Please retry the request...' (code 'Model generated function call(s).') ## Body Cause (Documented platform behavior): Server-side cap on tool calls per model turn; the message itself recommends retrying and including the message in the retry prompt. Fix status: workaround_only Limitations: - Single notebook output; the numeric cap is not documented in the source. Unknowns: - Exact per-turn tool-call limit Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/google-gemini/cookbook/f6c5d71cd8c3b0c0f385b8ade6c68a46f8876599/quickstarts/File_Search.ipynb (github_issue, unknown, reported_symptom): Saved output of an official cookbook notebook: google.genai._interactions.BadRequestError: Error code: 400 - {'error': {'message': 'Model generated too many tool calls. Please retry the request. If the issue persists, include this error message in the retry prompt ...', 'code': 'Model generated function call(s).'}}.
