Domain Description From Another Layer

[JoshBillings]

I am trying to return the domain description from another layer using an Arcade expression. I've tried the below, but it returns blank. Any tips? 

var basinPoly = FeatureSetByName($map,'Modeling_Basins')

var d = DomainName(basinPoly, 'BasinID')

return d

Thanks!

Unlike the DomainName function for a Feature, you'll have to provide the code to get back anything for FeatureSets

I am trying to solve the same problem.  Did you figure anything out?

I can get it to return the domain code and am thinking I might have to set up a series of if statements to change the code to the description.  It wouldn't be pretty but I am not getting any more ideas on it.
