Hi,

When adding Gemini or OpenRouter models to the copilot, this error occurs after a few messages (also in agent mode in the middle of work):

Sorry, your request failed. Please try again. Request id: 000-000-000
Reason: Request Failed: 400 [{ "error": { "code": 400, "message": "Invalid Authorization header.", "status": "INVALID_ARGUMENT" } } ]

This issue has been happening for the last few days.
