Describe the Bug

I’m unable to send prompts to cursor as shown by the screenshot. I’ve tried auto mode, different LLMs, and I’ve re-installed the application (i’m using a Mac). This bug applies to new chats and old chats. I haven’t exceeded my usage limits either.

Steps to Reproduce

Bug appears when trying to send prompts to a new chat or old chat

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this error seems to occur when a file that’s too large is open in the Cursor tab. If that’s the case for you, try closing the file and sending the request in the chat. If not, open the DevTools panel to check for any errors.
