You might get some seemingly strange or flippant reactions to this, and since you wrote it, I figured you might benefit from some insight into why some people might react negatively.

GP pointed out a tiny bug in good faith. Your reply asking them to fix the bug they found in your code comes across (to me, I'm sure not everyone sees it this way!) as a little presumptuous or entitled, I think because there's no expectation in this context that GP was signing up to "do work" (check out the repo, make a change, submit a PR to you) for your project.

A less... feather-ruffling response might have thanked GP for the bug report and maybe also mentioned the repo link in case GP or anyone would like to contribute, vs. straight-up asking GP to do the work.

Maybe someone else can weigh in with more detail. Or disagree vehemently with the vibes I'm trying to illuminate :)

And not trying to get too personal but this may be hinting at why so many of your jobs are incredibly short tenure.
