Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report and the Request ID, it helped us confirm it quickly.

This is a bug on our side. Our backend is sending header values to Anthropic that the provider is currently rejecting, which is why you’re seeing ERROR_PROVIDER_ERROR for your request ID. It’s not just you, it’s affecting many users on Opus 4.7. I’ve logged it internally, but I can’t share an ETA for a fix yet.

While we’re working on it, please try Sonnet 4.6 or GPT-5.5 as a temporary workaround. This path isn’t affected for those models. I’ll post an update in the thread as soon as I have one.

@MaxGlonk The issue should be gone now. Can you please try again and let us know?
