Unable to open app after installing on Caprover

[lvanv]

I deploy the app using the one-click app deployment option on Caprover. After the app deployment is completed, I try to access the site. I get a blank page with a message stating: "We're sorry, but something went wrong. If you are the application owner check the logs for more information".

Looking at the logs, it seems to be a problem with the articles_controller. Error message reads: "NoMethodError · undefined method `app' for nil:NilClass @app = article_setting.app ^^^^"
