Sorry, I mean on heroku. Try and whatever else buildpacks needed for your application (if any) ``` heroku buildpacks:clear heroku buildpacks:set heroku/nodejs heroku buildpacks:add heroku/ruby ```

It was a popular episode suggestion where due to compliance regulations (COPPA, CCPA, GDPR) they wanted to move from having an internal authorization mechanism to more of a hosted solution. Personally, I think in most cases Devise + Omniauth is suitable enough and I probably wouldn't implement Auth0. However, not having to worry about the authentication security portion is nice. Then again, if Auth0 is ever down, then from your end users' perspective, for all intents and purposes, you're site is also "down".

In the `vendor/assets/javascripts/plugins` folder, do you have the datatables, datetimepicker, moment, etc libraries in there?

If you want to silent some of the services, you can use something like this. It will disable the logs. https://docs.docker.com/config/containers/logging/configure#supported-logging-drivers ``` redis: image: redis:latest logging: driver: none ```

At the time of recording, it was Rails 5.1.1, but it should still be the same concept.
