Hi there,
I'm using the web version of the Experience Builder in ArcGIS Online.
When I try to include a web map or a secured service from our Enterprise (10.6.1) server I get following error:
SpoilerInvalid client_id
Error: 400

- The services and the web map are shared via a collaboration.
- Also: Once I close the error message window, the Experience Builder is not responding any resp. I can't add any more layers until I refresh the browser
Do I have to add the application to portal or to the trusted servers?
Cheers,
Marco
