Help with Arcade (date)

Laura — Thu, 07 Nov 2024 16:28:32 GMT

Still very new to Arcade and trying to copy from a script I saw on the community.

I get an error when using this: Expression must return a number value. Any help is appreciated! I am testing this out with the last edit date Esri field but will eventually be adding in another field that calculates the date of an inspection.

var edit_datetime = Date($feature.last_edited_date);

return result;

The script works if I put in another date field or just a date. Are you using this to calculate a field? If so, I'm guessing field is numeric while your script is returning text.

Not calculating another field. I switched to map viewer classic and the error went away. Wonder if there is a bug of some sort in map viewer. I am on 11.2

Are you using the output to drive symbology?

I've seen this error trying to use two fields for symbology. One needs to be numeric. might need to use a single expression, instead of combining with a field.

Yes I am. All based off of a date field.

If you have one field or expression on the layer using non-numeric values, you can't add a second field or expression using non-numeric values. The second variable must be numeric.

As the arcade expression seems fine and you're seeing an error in line with the above it could be this limitation you are seeing.

Try joining the two values into a single expression, or returning numeric values in this expression.

If you only want the single arcade expression driving symbology, can you share some screenshots on how you are applying it? Could be a minor workflow thing where you're adding a second variable instead of replacing the exisiting, or something specific to your version of Enterprise.
