Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

due to team workflow restructuring, most of the current work is in non-main branch.

when I run ‘hi’ in worktree/main, cursor doesn’t produce error. However, when I run ‘hi’ in worktree/non-main, cursor outputs "Connection failed. If the problem persists, please check your internet connection or VPN.
Request ID: 9dd274e5-2d95-4fb4-8551-848ebd3cd278
" and also output on the lower right coner of cursor screen saying “fail to create git worktree. fail to execute git.”

cursor agent cannot run git.

Steps to Reproduce

1. run ‘hi’ in worktree/main. no problem
2. run ‘hi’ in worktree/non-main. outputs "Connection failed. If the problem persists, please check your internet connection or VPN.
   Request ID: 9dd274e5-2d95-4fb4-8551-848ebd3cd278
   " and also output on the lower right coner of cursor screen saying “fail to create git worktree. fail to execute git.”

Hey, thanks for the detailed report.

This issue could be caused by a few things. To help investigate, could you share:

1. The Output panel logs (View > Output, select “Worktrees Setup” from the dropdown) - it may contain error details
2. The result of running git worktree list in your terminal
3. Whether there are any uncommitted changes in your repo
4. Whether your project has a .cursor/worktrees.json file

Also, please try this temporary workaround:

• Commit or stash all changes before starting the agent
• Check that Git is installed and available in your shell (git --version)
