peer_review branch does not retrieve GitHub PAT using gitcreds

[jooyoungseo]

Currently, the peer_review branch seems to retrieve GitHub PAT directly from .Renviron file.

I have securely saved my token using gitcreds::gitcreds_set() already.

When I tested using ghclass::github_test_token(), the peer_review version threw an error while the CRAN version and the main branch version were able to successfully retrieve the token as expected.

In other words, the peer_review version requires GITHUB_PAT variable in .Renviron file, which is a deprecated approach.

Yep unfortunately that is the case currently - I have not had a chance to backport the more recent changes in ghclass to this branch. I will try to do so later this week and hopefully it should go more smoothly.
