“error”: {
“code”: 400,
“message”: “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:search , position 2. please refer to https://ai.google.dev/gemini-api/docs/thought-signatures for more details.”,
