I'm working with a local-dev environment of Python GAE. In my code, I'm using the app_identity module to fetch the App ID Token for my project, like this:
scope = "https://www.googleapis.com/auth/userinfo.email"
app_id_token, expiry = app_identity.get_access_token(scope)
But when that pathway is invoked, I get this error thrown from the appengine module. It appears that when my project attempts to fetch an OAuth token to access Google Cloud services it is getting an SSL validation error on the URL used to get that token.

What confuses me is that this doesn't seem like it should be an environment configuration problem because it is SSL cert validation. However, neither of my teammates see this problem when we work from the same commit in our repository. I've tried re-cloning my repository, rebooting my machine, resetting my Docker setup. None of it has had an effect. Any advice into what's going on would be appreciated. Thank you.
