mobfriend.py failing checks on Github Actions

[deepfates]

When I push my branch to Github it fails checks due to a couple of #type: ignore checks in mypy:

Run pipenv run mypy sample_bots mc_util forest mobfriend contact imogen
  pipenv run mypy sample_bots mc_util forest mobfriend contact imogen
  shell: /usr/bin/bash -e {0}

Found 2 errors in 1 file (checked 28 source files)
Error: Process completed with exit code 1.

When I run the same command locally it does not have this problem, though for some reason many other files fail?

╰─>$ pipenv run mypy sample_bots mc_util forest mobfriend contact imogen                                                                                                   (base) 
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

I haven't edited mobfriend at all. I also see this happening in some other branches, specifically:
https://github.com/mobilecoinofficial/forest/runs/5238596966?check_suite_focus=true
https://github.com/mobilecoinofficial/forest/runs/5253050764?check_suite_focus=true
https://github.com/mobilecoinofficial/forest/runs/5262132498?check_suite_focus=true

My guess it might be local configuration environment configured differently from Github Actions?

wonder if this is related to prometheus/client_python#705 or hynek/prometheus-async#25
