Heroku Config Secret Key Base Error when running heroku open

Question

I get this error, when running "heroku open"

"Internal Server Error

You must set config.secret_key_base in your app's config."

I've tried everything in this thread:

Heroku Config Secret Key Base Error

• Set MyApp::Application.config.secret_token = ENV['SECRET_TOKEN'] in config/initializers/secret_token.rb
• Created a .env file with the contents SECRET_TOKEN=NKUd7gisd7fueAISDfg....
• Updated my .gitignore file to look like below

What else I have tried:

• I added: DemoApp::Application.config.secret_key_base = ENV['SECRET_TOKEN'] to secret_token.rb file

• Used figaro to create a application.yml file and pasted SECRET_TOKEN: 9489b3eee4eccf317ed77407553e8adc97baca7c74dc7ee33cd93e4c8b69477eea66eaedeb18af0be2679887c7c69c0a28c0fded0a71ea472a8c4abf3f0a19cb with my own SECRET_TOKEN

• ran rake figaro:heroku

I still get the internal server error. Apologies if this is a total nub question, but this is my first try with the "heroku open" command.

Thanks, David

Answer 1

Ok from heroku staff help turns out that my config/initializers folder was not pushing up to git.

Then these two posts solved it:

Config/initializers not pushing to repo

No submodule mapping found in .gitmodules for path

Best of luck

To set environment variables on Heroku, you need to use the Heroku Toolbelt from on local machine:

heroku config:set SECRET_TOKEN=f489b3eee4eccf317ed77407553e8adc97baca7c74dc7ee33cd93e4c8b69477eea66eaedeb18af0be2679887c7c69c0a28c0fded0a71ea472a8c4abf3f0a19ca

(Obviously, replace the token above with your own)

Then just make sure that you have MyApp::Application.config.secret_token = ENV['SECRET_TOKEN'] in your config/initializers/secret_token.rb file.

See Setting up config vars for a deployed application for further info.

Also make sure that you've added a secret_key_base entry for the production environment in your config/secrets.yml file:

production:
  secret_key_base: 527dacc0390e10df59278f1a18aa8ad14e429fa6ce522e5fb3b7ac358007dff4

Don't use the key posted here. You can generate a new one with a rake task and paste it into your config/secrets.yml file

bundle exec rake secrets
