Arcade Text() function not formatting dates in popup on Field Maps

NigelCharman

I have an Arcade expression on my popup which returns fields.

If the field type is an esriFieldTypeDate, we format the field as 'ddd DD MMM YYYY'. Opening the map in a browser the date displays correctly, e.g. 'Tue 19 Nov 2024'. However on Field Maps it's displaying as a long timestamp, e.g. '1731991427000'.

Is this a bug or am I doing something wrong?

 

Relevant Arcade code follows:

// Format field value based on type

function formatField(meta, fieldValue) {

if (meta.domain && meta.fieldType != 'esriFieldTypeInteger') {

return DomainName($feature, meta.name);

}

if (meta.fieldType == "esriFieldTypeDate") {

return Text(fieldValue, 'ddd DD MMM YYYY');

}

return fieldValue;

}

// Build final arrays in validFields order

var attributes = {};

var fieldInfos = [];

for (var v in validFields) {

var fieldName = validFields[v];

var fieldValue = $feature[fieldName];

 

if (!IsEmpty(fieldValue) && !IsNaN(fieldValue)) {

var meta = fieldMeta[fieldName];

var alias = meta.alias;

 

attributes[alias] = formatField(meta, fieldValue);

Push(fieldInfos, { fieldName: alias });

}

}

return {

type: "fields",

fieldInfos: fieldInfos,

attributes: attributes

};

Thanks for your answer @ChristopherCounsell.

It turned out to be much more obscure. I'd omitted to give you the preceding code, which I'd created from @PaulBarker's article Introducing Arcade pop-up content elements:

// Get field metadata

var fieldMeta = {};

for (var f in fields) {

    var fieldName = fields[f].name;

    if (HasKey(validFieldsSet, fieldName)) {

        fieldMeta[fieldName] = {

            alias: fields[f].alias,

            domain: HasKey(fields[f], "domain"),

            fieldType: fields[f].type,

            name: fieldName

        };

    }

}

The problem is that HasKey(fields[f], "domain") returns true on Field Maps, but false on Web Maps.

I've solved it by changing this line to also check for an empty domain value:

            domain: HasKey(fields[f], "domain") && !IsEmpty(fields[f].domain),

and the date fields now display as desired.

Any chance someone at ESRI could update the Introducing Arcade pop-up content elements article with this solution so others don't get the same problem?
