Experience Builder: Failed to construct 'IntersectionObserver': member root is not of type Element.

Hello everybody,
suddenly, without any modification to the configuration or to the web map, my experience no longer works correctly.

When I try to open the URL a page comes out with:

Failed to construct 'IntersectionObserver': member root is not of type Element.

The application is public, so if you want you can see it yourself. Here the link:

The same error appears when I try to edit from the experience builder.

The environment I use is the normal ArcGIS Online environment.

If I create a new experience, the error does NOT occur. If, on the other hand, I create a new experience from the existing one (the one with the issue) it will present itself.


Hope you can help me,

thank you!

Yo I have this exact same issue to. I'm building a testing framework for a react.js-based program using arcgis/core. Did you find a solution to this yet? I am not having any luck

Has anyone found a solution to this? I am having this issue with my Experience, but it is only an issue for medium screen devices. The large and small screen device versions of the Experience are working fine. Any help would be appreciated!
