How can I troubleshoot my Heroku deployment issues?

I'm having trouble deploying my app on Heroku. It keeps failing. What should I do?

First, check the Heroku logs by running heroku logs --tail in your terminal. This will show you any errors.

I see some errors related to missing environment variables. How can I set those?

You can set environment variables in Heroku using the command heroku config:set VARIABLE_NAME=value. Replace VARIABLE_NAME and value with your actual variable name and value.

What if I need to reset my database?

You can reset your Heroku database by running heroku pg:reset DATABASE_NAME followed by heroku run rake db:migrate to set it up again.

Thanks! Is there a way to roll back to a previous version of my app?

Yes, you can roll back to a previous release using heroku releases to see the list of releases, then heroku rollback VERSION_NUMBER to revert.
