Arcade: GetFeatureSetInfo function not defined error

[JustinReynolds]

No matter the profile I use the GetFeatureSetInfo function returns a function not defined error in ArcGIS Online and the Arcade play ground.

FeatureSet functions | ArcGIS Arcade | ArcGIS Developers

says

$layer originates from a feature service layer in a web map

is that the case? or should it be

$featureset originates from a feature class in a filegdb or mobilegdb

GetFeatureSetInfo($featureset)

Hey Dan,

Yes, the $layer originates from a feature service layer in a web map (it is a hosted feature service in AGOL).

Passing invalid arguments wouldn't present an error until code execution.

In this case, it just can't find the built-in function.  It never makes it to the point of checking for missing arguments because it doesn't recognize that the function exists (in a profile that supports said function).

In the new Arcade Editor, you don't see an issue until the code tries to compile.  Then you get the compilation error: "Compilation error - Line : x, y: Function not found".  It like calling a user defined function before you define it.

Is this function just Broken at the moment?  I think it might be.

new as of arcade 1.18 April 2022

perhaps yours isn't up to date

Yea I saw that as well. 

This is the same error that you would get if you tried to use an Arcade function that isn't supported in your current Arcade version.

So, I would expect to have this  issue in Enterprise (since we are using 10.9.1), but in this case I'm in AGOL, which should always be current. AGOL should be using Arcade 1.20 (November Release).

This issue is also present in the ArcGIS Arcade Playground if you want to test it out there.

Justin,

Any updates on this bug? I'm running into this same issue with ArcGIS Online. I'm stuck at the moment without this functionality. Just curious if this will be making its way into the next update by any chance.

Thanks!
