Something went wrong. Here's the specific error message we encountered: An error occurred while processing the request: [GoogleGenerativeAI Error]: Error fetching from https://generativelanguage.googleapis.com/v1beta/models/gemini-3-flash-preview:streamGenerateContent?alt=sse: [400 Bad Request] 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:web_search , position 2. Please refer to https://ai.google...."
