I am installing experience builder using ArcGIS Enterprise as per the instructions at ArcGIS Experience Builder install | ArcGIS Experience Builder | ArcGIS Developers .
However, when I update the Redirect URI (https://localhost:3001/) in the App Registration I get an error:
RequestError: Unable to load https://<our-portal-address>/portal/sharing/rest/oauth2/apps/<App-ID>/update status: 403
Can anyone tell me what I am doing wrong?
