Hello,
I have a problem of publishing hosted feature layer from ArcGIS Pro to our Portal on ArcGIS Enterprise.
The steps I used is shown in the following screen:

The error I got is here:

The error is:
"Server Response: ERROR: code:403, User does not have permissions to access 'hosted/served_health_facilities.mapserver'., Access to this resource is forbidden, regardless of authorization."
Knowing that I publish a feature class that is in relation with another table through relationship class in the project Geodatabase as shown in the first screen.
I highly appreciate your support on this issue very soon, since I have to meet the deadline.
Have a nice day!
