Gemini using tools #461
Description
I configured gemini as provider, the test model works, but when i try to use it i got
CompletionError: ProviderError: Google Gemini API error (400 Bad Request: unknown error)
This happens when the agent (or cortex) tries to use a tool.
- The google studio logs, only register the 200 requests on the logs, so it seems this error happens in the client
The workers' logs do not provide too much info:
