Hey @jklenzing do you have any ideas on why coveralls is rejecting some of the coverage info, but not others? It somehow got worse when I went from testing 4 python versions down to 3 :(

Searching on the web the fixes are to include things like run: coveralls --rcfile=setup.cfg --service=github which is already in main.yml for workflows.....
