Arcade Expression results display 'Data Error' in 'Show Table'

We have configured an Arcade expression in a Table popup. There is a 1:M relationship between a point layer and this Table. The resulting value of the Arcade expression is successful. However, when viewing the Table's attribute table in the map viewer, a blue hyperlink is displayed in the expression attribute column with the value 'Show', but when clicking it displays 'Data Error'.

When saving the map and attempting to view the table using the Web AppBuilder Attribute Table widget, no records display when viewing the Table's attributes.

The following expression returns a successful value, but displays as 'Data Error' when viewing in the attribute table.

var signTable = FeatureSetByRelationshipName($feature, "RoadSign");

var results = "";

for (var r in signTable) {
    results =+ r.SignID

return results

Need to be able to view the related Table with attributes grabbed from the related feature layer.

Thoughts or ideas?
