random python exception on publish

[zoranbosnjak]

I have observed a situation where the publish action had succeeded (I've got a new version on test.pypi.org), but the action reported error at the end and the run is marked as failed. This problem was only observed once and I am not able to reproduce it. Nevertheless, it looks like an internal error from this action (python exception comming from requests module). The previous (manual) and subsequent (scheduled) actions were without any error. A full log of the failed run is attached. I hope the maintainers will get an idea of what went wrong from the log file. Please also let me know if there is a problem in the workflow description or if there is anything I can do to help reproduce or narrow down a problem.
