✕ mypy failed.
I get this even if I run on all of 
src/python/pants::
So it’s not an artifact of running on a subset of files or whatever
CIs seem to be passing
h
I wonder if it's from running MyPy with a different Python version perhaps?
h
Ah could be
I’m on 3.9
Apple ARM and all that
Grr
Well at least it won’t break CI
h
that's what i use. I ran 
./pants check src/python/pants/engine/target.py
on main and it passed
h
huh…
And that does fail for me locally as well
but my change didn’t touch that file
Although it doesn’t fail for me on main locally
Oh, NM I am a dummy

That was a real error
