Export to CSV broken when using Arcade Attribute Expression

Hi all,

I have a web app utilizing the "Export to CSV" functionality in the Attribute Table widget. I have insured this is checked-on in the widget settings.

I am also using Arcade Attribute Expressions to calculate some fields in the pop-up that will also be available in the attribute table and subsequent CSV. This works as expected until I add the expressions below. Then the export to CSV freezes and never completes. The expressions buffer a linear feature and return the lat/long of the centroid. 

Latitude
var PatchBuffer = Buffer($feature, 10)
var PatchCentroid = Centroid(PatchBuffer)
return round(PatchCentroid.Y, 6))

Longitude
var PatchBuffer = Buffer($feature, 10)
var PatchCentroid = Centroid(PatchBuffer)
return round(PatchCentroid.X, 6)

Attibute expressions are being leveraged for a number of other fields and these are exporting as expected. The exports fail when the above expressions are added.

I have isolated the problem but am a little lost on how to resolve it. Any ideas are welcome.

Have you tried just using the geometry attributes of the feature?  Is the buffer doing anything here?

i.e

var lat = geometry($feature).y

var lon = geometry($feature).x

Hi,

The features are linear, so they do not have an explicit X/Y available.

The buffer is creating a polygon to get the centroid lat/long. 

It appears this is a known bug, BUG-000131959. I was hopeful someone had a workaround.
