Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report.

That’s odd behavior. A case-sensitive exact match search for getHandlersForToken should’ve returned results. The -i flag shouldn’t affect an exact match.

I’ll pass this to the team to investigate.

A couple quick questions:

  1. Is this consistently reproducible, or was it a one-off?
  2. After restarting Cursor and starting a new chat, does the issue still happen?
