Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. It looks like the problem is a JSON syntax issue in your request body. There’s a trailing comma after the repository URL, which makes the JSON invalid.

Because of this trailing comma, the server rejects the request and returns the generic “internal error” message you’re seeing. Removing that comma should fix the issue.

Let me know if this resolves it!
