Description
The models work fine in chat mode, but attempting to call a gemini model from agent mode gives this error when called from aistudio/vertex:
"[{\n \"error\": {\n \"code\": 400,\n \"message\": \"* GenerateContentRequest.tools[0].function_declarations[10].parameters.required[2]: property is not defined\\n\",\n \"status\": \"INVALID_ARGUMENT\"\n }\n}\n]"
& this error when called via openrouter:
400 Provider returned error
the issue persists across latest build & previously working builds. the error first appeared after the global outage on 12th June so I believe it may be related to some change on googles end
have not had the chance to test this on another system so there is a chance this is local to my machine
To reproduce
https://github.com/user-attachments/assets/7a2ebdea-5d38-4d60-8935-8e5181bc9210
- Select a google gemini model from one of the listed providers
- select agent mode & send message
- observe error message
