google3+Error, making it unusable

Non-retryable error (HTTP 400): HTTP 400: Gemini HTTP 400 (INVALID_ARGUMENT): Function call is missing a thought_signature in functionCall parts. This is required for tools to work correctly, and missing thought_signature may lead to degraded model performance. Additional data, function call default_api:clarify , position 76. Please refer to https://ai.google.dev/gemini-api/docs/thought-signatures for more details.

extent analysis

TL;DR

The most likely fix is to include a thought_signature in the function call to resolve the HTTP 400 error.

Guidance

  • Review the function call to default_api:clarify at position 76 and ensure it includes a valid thought_signature.
  • Check the Gemini API documentation at https://ai.google.dev/gemini-api/docs/thought-signatures for the correct format and requirements for thought_signature.
  • Verify that the thought_signature is correctly formatted and included in the function call to prevent degraded model performance.
  • If issues persist, consult the Gemini API documentation for additional troubleshooting steps.

Notes

The provided error message and documentation link suggest that the issue is related to a missing thought_signature in the function call, but without more context, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Include a valid thought_signature in the function call to resolve the HTTP 400 error, as this is a required parameter for the Gemini API to work correctly.
