Arcade Data Expression runs in playground but not in "live" dashboard

Hello -

I'm trying to list averages from featureset variables and display them in a list. My script runs in the ArcCade or "Data Expression" playground but when I try to use it for an element on my dashboard it shows a message "unable to execute script". What am I doing wrong?

thanks in advance for any guidance!

Thank you!! This got me almost exactly what I needed. Just had to rewrite the out_dict to this:

var out_dict = { fields: [ { name: 'Name', type: 'esriFieldTypeString' }, { name: 'Score', type: 'esriFieldTypeDouble' } ], geometryType: '', features: result }
