Help me please, I've finished 11 chapter of rails tutorial, deployed my app to heroku (locally it worked perfect) and it crashing all time. I'm using rails 5.2.2
After execution of command $heroku run rails console I'm receiving this:

Here are the docs for environmental security on rails https://guides.rubyonrails.org/security.html#environmental-security

In your case you should have this files

config/master.key

config/credentials.yml.enc

If not you can generate those with this:

rails credentials:edit

Now the file master.key is ignored by your version control because is the key rails use to decrypt the .enc, just commit your credentials.yml.enc and push it to heroku.

For master.key on heroku you can define the environment variable RAILS_MASTER_KEY on your heroku app and put the value of master.key on it.

Now to access the environments variables that you defined on your .enc file you must access through Rails.application.credentials
