Is a Query Layer now a Dashboard Indicator Control Requirement

Question

I was updating the data source feature class for a Dashboard sourced from a referenced mapservice originally built in enterprise 10.7.1.  The data source is no longer accessible from the mapservice according to error message.

Does the data source now need to be a query layer?

Query layers can feel a bit confusing in dashboards because they blur the line between data source and control. From what I’ve seen, they don’t automatically behave like indicator controls unless they’re exposed through a feature layer or view that dashboards can interact with. Once wrapped properly, they work fine, but expecting them to act like native controls usually leads to frustration.

When adding fields to a versioned enterprise gdb feature class, do you always unversion first, add fields and the re-version to make sure evw file is created properly?

So I exported the problematic SDE roads line feature class to a file gdb and created a service from the file gdb feature class.  Now I can use a Dashboard indicator.

As such, what could cause the same SDE feature class not to work in a Dashboard indicator?
