I can't seem to deploy this rails application after adding devise / doorkeeper.

Generally this means that there is a problem with your RAILS_MASTER_KEY. It is a common initial setup problem, but once it works it tends to keep working.

The following might fix it:

fly secrets set RAILS_MASTER_KEY=$(cat config/master.key)

(Non bash, non WSL2 windows users will need to replace the value after the = sign with the contents of config\master.key)

If that doesn’t work, things to check:

  • Does bin/rails credentials:edit work?
  • Do you have a config/credentials/production.key?
