Arcade expression for pop-up works correctly in Web Map but not in VertiGIS Studio App

Hi All,

I am new to VertiGIS as well as a beginner when it comes to arcade.  I have spent several days trying to configure a pop-up to function appropriately and finally got it to work in my web map but when I opened it in VertiGIS it did not work.

I have a field in a layer that contains a URL to documents stored in Laserfiche.  However, some features do not have any documents so that field is blank.  I originally just put the field as a hyperlink in the pop-up.  It worked fine when there was a record, but if there was no value in the field it just opened the web map again.

What I want to happen is when a user clicks on a feature and there are no documents it states “No Documents Available” and when the field does contain a URL it provides a link to click on.  

This is my arcade expression that works in the AGOL web map:

var attachment = $feature.LF_Report

var result = “Documents: No Documents Available”

if (!isEmpty(attachment)){

  result = `<p>Documents : <a href="{LF_Report} ">Link</a>

    </a></p>`

}

return {

  type : "text",

  text : result

}

Below is what it looks like when a site does/does not have documents in the web map.

However, when I click on a site in VertiGIS Studio it only displays “No Documents Available”

Being new to VertiGIS and arcade I am not sure where my issue is.  Any advice would be greatly appreciated, thanks!!
