Describe your issue

I'm currently running a project with docker. The root of the project contains /frontend folder where we have our Nextjs application running.

When I go into the running frontend container's exec shell and run npx @tailwindcss/upgrade@next i'm getting the following errors:

The GIT repo error is logical, because the /frontend folder is not a git repository itself, the root of the project is however.

Is there a way to fix the issue and get the upgrade tool running? Or am I stuck with manually upgrading?

@first-andy Any reason to not start the tool from the .git repository root? We do rely on things like .gitignore etc. to scan the proper files.

Check, did not know that. After running it from the project root and deleting my /node_modules folder I got the tool to work.
