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

1

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:

At build time, your credentials will be nil. Your credentials will be available at deploy time.

Assuming that you don’t need stripe at build time to build your assets (HTML, CSS, JS), all you need to do is add an if statement to your initializer to check if your credential is nil before proceeding.

If you need further help, post the source to this initializer.

config/initializers/stripe.rb

require 'stripe'

Stripe.api_key = Rails.application.credentials[:stripe][:secret]
4

Try:

require 'stripe'

if Rails.application.credentials[:stripe]
  Stripe.api_key = Rails.application.credentials[:stripe][:secret]
end
5

It solved the problem regarding stripe, but now I’m getting this error:

You are getting an error in an initializer, but you would need to see more of the stack trace to debug it. Try looking at your dashboard to see if more information is there, otherwise run fly logs. See Existing Rails Apps · Fly Docs for more information.
