Redis – Rails application after deploying on Heroku gets 500 error can't find the error source in log

As a programming beginner, I deployed a rails app for the first time on Heroku. I got a 500 error and I can’t find the source. If you could help me to find it in the log, that would be great. Please let me know what additional info I need to share to debug.

It’s not long, much to check

    This is the error: ActionView::Template::Error (Must supply cloud_name in tag or in configuration)

    It seems you didn’t configure your CLOUDINARY_URL, as explained here: https://cloudinary.com/documentation/rails_integration#configuration

    How to do it in Heroku: https://devcenter.heroku.com/articles/config-vars

    This is the extract, you should look for the “FATAL” identifier.

    I think you forget to configure the Heroku app in your rails app.
    You can config it using “Heroku config”.
    OR can follow the link provided by @beauraF.(https://devcenter.heroku.com/articles/config-vars).
