found the issue - i missed the turning of a expression into a generator, will release a fix including a test soon

[chrisphilip322]

Any chance we can reopen this issue until you release the fixes @RonnyPfannschmidt ? My build at work still can't build anything that uses setuptools_scm

[RonnyPfannschmidt]

@macbeth322 sure, the plan was to do a release earlier, but i botched the release process while doing that - im going to fix it this weekend

[RonnyPfannschmidt]

closing as 3.0.4 got released
