error by FeatureSetByPortalItem in data expression?

[MaryamRojhan]

I dont know why i get failed to fetch error when I use FeatureSetByPortalItem in data expression in Dashboard. 

I get another error when I remove www from the portal url

var p = Portal('https://arcgis.qed.de');

var fs = FeatureSetByPortalItem (
p,
'56370e2e39b54872a7fa83783db301d3',
0,
["status_text"],
false
);

I would be very greatful if ayone can help me in this case.
