Web App editor hangs on web map created in ArcGIS Pro, unless I resave

Question

In ArcGIS Pro, I modified I map so I could group multiple layers, then shared the map.  When I bring up the map in the new Map Viewer in ArcGIS Online and simply do a Save (without any mods to it in Map Viewer), I get a red-bordered dialog box at the bottom that says "Error:  There was an error."  No other info.  Analyze in ArcGIS Pro only produced "24125: Service layer's item ID will not be included" which I read is innocuous.

Furthermore, if I try to use the map in my web app (in Web AppBuilder), WAB hangs on it, no matter how long I wait.

The only way I can save the map is if I am in MapViewer Classic, do Save of it in there, and then I am also able to load the map in WAB!   Unfortunately, I lose the grouping of layers.

I gather WAB hanging on the map may be due to "Error:  There was an error" but if I knew what the error was, I'd be able to resolve!

Yes, I ran into the same frustration a couple of months ago.  All of the nice new functionality in the new map viewer (grouped layers and more advanced symbology, etc) can’t be used in WAB.   I understand that WAB uses the 3.X version of the JS API, and the new map builder 4.X.

I tried using EB instead but lost some of the fundamental functionality I was using in WAB, so reverted back to that…

Agree that products are being pushed out before they should be, which is a shame, as there is a lot of great functionality in the ‘nearly ready’ pile!

Thank you for the clarification, Helen!  I looked at Experience Builder FAQ and it seems to me it is nowhere near up to snuff w/r/t Web AppBuilder.  Again, another frustration I have with Esri in that they are pushing out products that, to me, are not ready for prime time.

I am using Web Appbuilder to make use of widgets and other features.  Since it appears the only way I can implement groups layers is in ArcGIS Pro, it seems I cannot do so 😞

I’m afraid WAB builder can’t handle grouped layers. You’ll need to use experience builder for that (although that comes with drawbacks as you can’t achieve everything you can in WAB…)
