Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi Drew!

I looked into your request ID and found that the testing environment is being created, but the install command in your .cursor/environment.json is failing with exit code 1. This causes the generic [invalid_argument] Error you’re seeing.

The UX here isn’t great, and we can improve it. Hopefully, this at least tells you were to look next.
