See this announcement, currently still working, but is throwing this Warning: The set-output command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/ in the actions log.

Thank you! I'll look into what needs to be changed.

I think this would be fixed by #93

[g105b]

#92 is now merged. Feedback is appreciated.
