git push heroku; Please double-check your credentials and correct them

Question

I recently changed my Personal Access Token on GitHub, and I think I've put the new token in all the right places... but maybe I am missing a place?

The problem:

$ git push staging my_cool_branch:master

Files (that I am aware of) with Personal Access Token:

$ cat ~/.bundle/config 
---
BUNDLE_RUBYGEMS__PKG__GITHUB__COM: "bart_simpson:ghp_nJabIP9JjPe7KOwgDrkiJextJggm114MZh7f"
BUNDLE_HTTPS://RUBYGEMS__PKG__GITHUB__COM/PRIVATE_ORG/: "bart_simpson:ghp_nJabIP9JjPe7KOwgDrkiJextJggm114MZh7f"

and

$ cat ~/.gem/credentials
---
:github: Bearer ghp_nJabIP9JjPe7KOwgDrkiJextJggm114MZh7f

and

$ cat ~/.gemrc 
---

Ah, see ~/.bundle/config above?

The solution was that I also had to set BUNDLE_RUBYGEMS__PKG__GITHUB__COM to the new token in staging:

heroku config:set BUNDLE_RUBYGEMS__PKG__GITHUB__COM=bart_simpson:ghp_nJabIP9JjPe7KOwgDrkiJextJggm114MZh7f

...which, btw, means that you must also set it in .env:

BUNDLE_RUBYGEMS__PKG__GITHUB__COM=bart_simpson:ghp_nJabIP9JjPe7KOwgDrkiJextJggm114MZh7f
BUNDLE_GITHUB__COM=x-access-token:ghp_nJabIP9JjPe7KOwgDrkiJextJggm114MZh7f
