We are using Github to host our repo and the authentication mechanism is through an app.
The git pull randomly fails with the following error. Emphasis on “randomly”, it works 90% of the time but we keep seeing this error randomly.

I work in a very large monorepo, so by default the fetch configuration is constrained to avoid pulling down thousands of branches and slowing down git (i.e. fetch = +refs/heads/master:refs/remotes/origin/master)
