I am working with arcade expressions for a popup window and after only getting the error below I realized something else might be going on. Also I notice that no Global variables are available in the expressions reference pane?!
This is the error I get for any simple function...
Execution Error:Cannot read property 'root' of null
I have no problem doing this in other maps.
I am working with a simple "Parks" point layer, and the map service and feature service have the same result.
Here is the AGOL item
it just references my AGS map service here
and here is the feature service of the same ()
Please help me figure this out, I'd like to build my popup with arcade expressions
UPDATE 1: The error in firefox is Execution Error:e._profileGlobals is null (a little more helpful perhaps?!)
UPDATE 2: I uploaded the feature class to AGOL hosted and still the same? here is the AGOL hosted item.
