Error: Access not allowed request

When I tried to add feature layer to experience builder, I got error pop up shown below image.

As shown on above image, the feature layer I've tried to add is my content.

Does anyone have an idea of this issue?

Hi Su-hyun,

It looks like an access issue. Are you using expereince.arcgis.com to access a map service from your portal? 

Thanks,

David

Thanks for the reply!

I use built-in exprience builder in Portal for ArcGIS 10.8.1

Also, the feature layer is exist on same portal.

Thanks,

Su-hyeon.
