Hi @cstork
You cannot call a query (cannot use .trigger()) from within a components data source. While you can use Javascript inside of {{}} as a data source, it should be one liner, self-evaluating code. Triggers, promises, and more complex code should be moved to a Javascript query that is triggered on page load, on success of a resource query, or based on some user action.

This post shares some Javascript best practices.
