ERROR [build 9/9] RUN SECRET_KEY_BASE=DUMMY ./bin/rails assets:precompile

[furukawaeiichi]

I am a student in Japan and just started learning programming.

ruby "3.2.2"
gem "rails", "~> 7.0.4", ">= 7.0.4.3"
gem "omniauth-twitter2"
gem "omniauth-rails_csrf_protection"

I got the following error when I entered “fly deploy”.

ERROR [build 9/9] RUN SECRET_KEY_BASE=DUMMY ./bin/rails assets:precompile when running fly deploy

I’ve been trying to deploy some changes on my rails app and get the following error: ERROR [build 9/9] RUN SECRET_KEY_BASE=DUMMY ./bin/rails assets:precompile I’ve integrated stripe to my app and deleted credentials I had on ENV file and added them again using EDITOR=vim rails credentials:edit. After running fly deploy I get the following: > [build 9/9] RUN SECRET_KEY_BASE=DUMMY ./bin/rails assets:precompile: #19 0.947 /usr/local/lib/ruby/2.7.0/net/protocol.rb:66: warning: already initializ…

I think there is a problem with this file, how should I fix the code?

config/initializers/omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter2,
          Rails.application.credentials.twitter[:client_id],
          Rails.application.credentials.twitter[:client_secret],
          callback_path: "/auth/twitter2/callback",
          scope: "tweet.read users.read"

  OmniAuth.config.on_failure =
    Proc.new { |env| OmniAuth::FailureEndpoint.new(env).redirect_to_failure }
end

I entered “EDITOR=vi rails credentials:edit” and wrote the secret key as follows

twitter:
  client_id: ********
  client_secret: ****************

Or another file?
https://github.com/furukawaeiichi/CREDO_QUEST/compare/main...feature/login

Could someone please advise me on this?

@furukawaeiichi

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter2,
          Rails.application.credentials.twitter[:client_id],
          Rails.application.credentials.twitter[:client_secret],
          callback_path: "/auth/twitter2/callback",
          scope: "tweet.read users.read"

  OmniAuth.config.on_failure =
    Proc.new { |env| OmniAuth::FailureEndpoint.new(env).redirect_to_failure }
end

This problem is described here.

The fix is to surround the above code with:

if Rails.application.credentials.twitter
...
end

What’s happening here is that both assets:precompile and your deployed application load your configuration, but only your deployed application has access to, and needs, your twitter credentials.

Dear rubys
Thank you for the article and advice!
It was very easy to understand.

I have successfully deployed it.
Thank you very much for your kindness!
