• To access AGOL, use the url https://www.arcgis.com
• Don't use reserved names (Portal) as variable names. It's no problem here because you don't need to call Portal() anymore, but you could run into prroblems with other expressions if you let that become a habit.

var p = Portal("https://www.arcgis.com")
var cities = FeatureSetByPortalItem(p, "0218468f0d8f40daa9b5aa79b88ca961", 1, ['admin4_en2', 'primary_destination', 'parentglobalid'])
