Missing credentials after deploying datamart from development to test

[sedkimic]

I have a datamart as part of deployment pipeline.  After deploying the datamart from development to test, the refresh fails and I receive a "there was a problem refreshing your datamart" message.  When I open the query editor for the datamart in the test environment, all the querys connecting to external data sources, i.e. on-prem databases, are returning "we could not evaluate this query due to missing or invalid credentials."  When I select the "configure connection" dialog I see that the gateway connection is properly referenced.

The datamart refreshed (and continues) to refresh properly in the development environment.  How do I get it to refresh properly in the test environment?

Nevermind - figured it out.  I had multiple data sources that were being consumed in the datamart.  I had to update the connection for each one (although the UI suggests that they are already configured correctly) before any of the queries would work.
