Arcade: How do I use a variable as the field list parameter for FeatureSetById?

Question

I'm trying to pass a variable for the fieldList parameter of the FeatureSetById function. See line 13. If I remove [relFSAtts] from line 13 and return all fields, my script works fine. But when I use a variable in an attempt to retrieve only some fields, no featureset is returned. My console output looks correct, so I'm not sure why it's not working 'ParentTapNumber', 'CustomerName', 'CustomerContact'‍ Any ideas on how to make this work? I want to avoid hard-coding attributes where possible, because this is a script I'll use frequently. //Set the name of the related table, foreign key field, and attributes to include in the feature set var relTable = "MyTableName_5212" var relKey = "ParentTapNumber" var relAtts = "'CustomerName', 'CustomerContact'" var relFSAtts = "'" + relKey + "', " + relAtts console(relFSAtts) // Get feature attributes from parent table and build query to get related records var featID = $feature.TapNumber; var featQry = relKey + " = '" + featID + "'"; // Get feature set from related table based on ID in map, and filter it with the query var fSet = FeatureSetById($map,reltable,[relFSAtts]); var fSetFilt = Filter(fSet, featQry); //Declare placeholder variables for each attribute, and declare utility variables var CustomerNameResult; ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Rob Blash and PKlingman-esristaff , You will need to provide an Array (list) of fields. You can do this like this, if you really want to do it... //Set the name of the related table, foreign key field, and attributes to include in the feature set var relTable = "MyTableName_5212" var relKey = "ParentTapNumber" var relAtts = "CustomerName,CustomerContact" var relFSAtts = Split(Concatenate([relKey, relAtts], ","), ",");‍‍‍‍‍ Resulting in: ["ParentTapNumber","CustomerName","CustomerContact"]‍
