Just from running coveralls

[FinchPowers]

I forced the installation of coverage==4.4.2 and it fixed the issue.

I am having the same error, but mine is KeyError: 29770. Tried @FinchPowers's solution but didn't work.

UPDATE: I switched to coveralls-python and it just works.

@kmkurn You should check the package description: coveralls-python (0.0.1) - This is a package used to demonstrate a vulnerability

[kmkurn]

@GuillaumeSmaha On pip it's listed as coveralls. You should check the link I posted above.
