Yep I have seen this issue recently. For reference, this is the error

Could you split the pyproject change into a separate commit?

Discussed with @GDYendell : We think that solving #159 should fix #137 , so this PR may not be required. I will draft this PR for now, and then close it if we can fix it in that other way

[GDYendell]

Fixed in #182
