Question

This error is appearing in my heroku logs and I’m not sure what is happening. The app is not functioning correctly and is breaking in many different locations. The weird thing is that this started happening out of no where. No changes have been made in the last 7 days. Everything was functioning correctly on Friday which means this error started occurring sometime over the past 4 days.

Are there any gem dependencies that may have been changed/updated over the weekend that could be causing this error?

Answer 1

The problem was that the Heroku gem was deprecated so I replaced the gem “heroku” in the gemfile with “heroku-api”
