Rails 7 - Heroku push : Error Build failed

Heroku push : Error Build failed

I am developing a Ruby on Rails 7 web application that uses the omniauth-linkedin-oauth2 gem for LinkedIn authentication. The app works fine locally with the LinkedIn credentials defined in config/credentials.yml.enc. However, when I try to deploy the app to Heroku, I get the following error during asset precompilation: vbnet

NoMethodError: undefined method `[]' for nil:NilClass config.omniauth :linkedin, Rails.application.credentials[:linkedin][:client_id], Rails.application.credentials[:linkedin][:client_secret] 
I have checked that the LinkedIn credentials are correctly set up in both config/credentials.yml.enc and on the Heroku app’s config vars.

First of all I would ensure that credentials have expected structure, if they do, did You set RAILS_MASTER_KEY environment variable on Your heroku app ?
All the details how to do it You can find on following post https://stackoverflow.com/a/62011825/3142249
