Figure out why pypi releases do the release but then fail

[modelmat]

It seems to be uploading the release twice? No idea why

Maybe this helps to analyze the problem

I'm not sure, but my guess is it is related to the triggers:

sphinxcontrib-drawio/.github/workflows/workflow.yml

Lines 2 to 13 in 373b54f

	on:
	pull_request:
	branches:
	- master
	push:
	branches:
	- '*'
	tags:
	- '*'
	create:
	tags:
	- '*'

Because the workflow sometimes runs several times for single commit, for example when I pushed and tagged 373b54f:

source: https://github.com/modelmat/sphinxcontrib-drawio/actions

In this case, it one is a create event and the other two are push events (one push event isn't tagged, so doesn't trigger a release). So I'm thinking maybe the create tag event is in a race event with the push tag event and the fix is to only trigger tags on push or create (not sure best practice).
