"NoMethodError: undefined method `deep_symbolize_keys'" when trying to deploy my application

Hey I followed the deploying guide for Ubuntu 20.04 LTS. When deploying my application I get the following error. Googling around I haven't been able to locate any leads on what to do... anyone have a suggestion to try? Thanks!

My current project I'm attempting to deploy is Rails 5.1.6 as well.

If you read the logs, you'll see it crashed while loading secrets.

/home/deploy/bane/shared/bundle/ruby/2.6.0/gems/railties-5.1.6/lib/rails/secrets.rb:24:in `parse'

So my guess is that you're missing secrets on your server or they're empty or not formatted correctly.

Thanks Chris!
