GitHub Actions Failed to Deploy changes to Heroku

Question

I am using GitHub Actions to Deploy my JavaScript to Heroku and it is working fine as expected. However, when my GitHub Repository is recently updated my GitHub Actions failed stating the following. I have never updated the Heroku Git Manually, how can this issue happen?

Answer 1

tl;dr; You need to regenerate your Heroku API key and update it in your GitHub repo.

Heroku suffered a security incident earlier this year. They have since begun reseting all of their users' passwords which in turn invalidated the API access token you may have created. This is likely the reason for the error you are seeing.

To fix this:

1. Use either the command link or the Heroku site to generate a new API key.
2. Update your API key in your GitHub repository by going to Settings -> Secrets -> Actions and updating the HEROKU_API_KEY.
3. Optional: You may also need to reenable automatic deploys by going to your app on Heroku, clicking Deploy, and reenabling Automatic deploys.
