Multiple Database Setup Github Actions

I have defined a secondary external database in my Rails application for read-only purposes. Thus for testing, I setup a local database and plan to mock data within my test examples. Connecting to the database and running tests locally work great. However, when running the CI tests, the secondary database fails to setup due to the following error:

I believe this to be a configuration setup issue within the ci.yml file, and am not sure how to configure this properly.

The problem was solved by matching the username/password fields between both ci.yml and database.yml.
