Hi @OrderAgent could you please confirm if you were using Gemini API key and which model you used.

As shown in the video, I confirmed issues with gemini-2.5-pro and gemini-2.5-flash when using the Gemini API key.

No API keys are registered for other models.

When applying to a file, if you select a model other than Gemini or disable the Gemini API key, the application will succeed.

I have sent all the details to our dev team.

Is this fix really that difficult?
Or am I the only one experiencing this problem?

It worked when using cursor 1.0.0.
