I am trying to add a Feature Layer (add Data) in Experience Builder but I become an Error :
Error: Access not allowed request
it happens only by Feature Layer, for example Webmaps are working normally.
I tried to add any of Layers not only from My Content.
Any Idea why it happens?
Did you get a resolution to this error? We are experiencing the same issue. We just upgraded to 10.8.1. We can also add a web map that contains the same feature layer without any errors.
