问题 I added the key into heroku config var, but I'm still getting the error. Is this the correct way? I ignored secrets.yml as I read from other sources that its not a good idea to push this to the public. in the heroku config var: [key] SECRET_KEY_BASE [value] 3280570382948240938 in secrets.yml production: secret_key_base: <%= ENV["SECRET_KEY_BASE"] %> What am I still doing wrong?

(example: in .env.development: FOO=BAR and in .env.production: FOO=BAZ, in development mode process.env.FOO would be BAR, in production i'd be BAZ).
