Trying again doesn’t resolve the problem.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report! Could you try creating a new chat? Also, could you let me know which model you’re using?

[ElVi]

Hi, a new chat does work. It’s set to auto, before it was claude-sonnet.

[deanrie]

If you switch models within a single session, it might lead to unexpected errors. So, I recommend sticking to one chat, one model → one task, to ensure everything runs smoothly.

[ElVi]

Going back to the original model, didn’t resolve the error, sadly

[deanrie]

Unfortunately, this happens. You can create a new chat with the previous context by using the past chats feature.

Alright, thanks for the workaround solution!
