`brew doctor`:
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: You have uncommitted modifications to Homebrew/homebrew-core.
If this is a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be undone
should you later need to do so for some reason.
  cd /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-core && git stash -u && git clean -d -f

Verification

• My "brew doctor output" says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

I'm trying to audit my package for submission, but brew audit seems to be giving an error

What happened (include all command output)?

It doesn't error when HOMEBREW_NO_INSTALL_FROM_API isn't set, but when it is, I get the following output on macOS, Linux, and the build CI:

user@hostname:~$ HOMEBREW_NO_INSTALL_FROM_API=1 brew audit --new-formula squiid
 
Error: undefined method `<' for nil:NilClass

The issue here is that https://gitlab.com/ImaginaryInfinity/squiid-calculator is a group, but this audit is expecting it to be a project repo (the actual project is at https://gitlab.com/ImaginaryInfinity/squiid-calculator/squiid).
