#19368 Pyright fails in Github action Issue created by CJTurpie Describe the bug When running

pants check ::

as part of a GitHub action, sometimes (but not always), pyright fails the check, it looks like its failing to find any of the 3rd party imports with lots of errors such as (file path redacted):

/tmp/pants-sandbox-zZouYc/.../models.py
  /tmp/pants-sandbox-zZouYc/.../models.py:7:6 - error: Import "pydantic" could not be resolved (reportMissingImports)

There are hundreds of these errors, seemingly for every third party import, any idea on how to start debugging this or how to resolve it? Pants version 2.16 OS n/a running on Github action Additional info Relevant parts of action yml file
