AGOL Update - Pop-up fields with Arcade expression no longer displaying

[Espressoz]

Hi all,

I have a simple map where the main point data are pulled from a live/referenced CSV published via Google Sheets. I used an Arcade expression (through the "Add Content > Arcade" block) to prevent any fields with null/empty string records from displaying in the pop-ups (styled as just the default attribute table). Until the update, it was working perfectly.

After the update yesterday, the correctly configured table will initially display for a single point, but when I click on other features (or back to that original point), where the table should be in the pop-up is completely blank. I can reliably reproduce this when I toggle "Enable pop-ups."

When I test run the code, the correct output appears. I'm definitely a beginner with Arcade and got the code below from another user, modifying it for my map. I've already tried quite a few workarounds, but nothing is producing what I had before -- it's just blank. The Text block that precedes the Arcade expression still displays normally.

Is this an update bug, or should I be doing something different? I would appreciate any help. Let me know if I can provide further details. Thank you!

Here is the code that previously worked for me:

var attributes = Dictionary($feature)["attributes"];
var fieldInfos = [];
var attributeValues = {};

var excludeFields = ["Field1", "Field2", "Field3"]; //Excluded fields, null or not null

var layer_schema = Schema($feature);
var fieldAliases = {};

for (var i = 0; i < Count(layer_schema.fields); i++) {
    var field = layer_schema.fields[i];
    fieldAliases[field.name] = field.alias;
}

for (var key in attributes) {
    var value = attributes[key];

    if (!IsEmpty(value) && value != "" && IndexOf(excludeFields, key) == -1) {
        var displayName = key; // Default to field name
        
        // Use alias if available
        if (HasKey(fieldAliases, key)) {
            displayName = fieldAliases[key];
        }
        
        Push(fieldInfos, { fieldName: key, label: displayName });
        attributeValues[key] = value;
    }
}


return {
    type: 'fields',
    fieldInfos: fieldInfos,
    attributes: attributeValues
};
