My coworker created a view layer of a hosted feature layer. I tried adding it to a map viewer classic app to view in web app builder but got this error message, "An Error occurred loading this layer".
I also had the same error in the new map viewer for an existing map. I also had the error viewing the one layer in map viewer in a new map.
I was using google chrome and tried deleting my history and cache because I saw other people suggest that but I still have the error message.
I tried using firefox and it didn't work either.
I clicked inspect in chrome and here are some error messages:

My coworker who created the view layer just opened it in map viewer and got the same error that I did, she has a different computer, so I think it is related to the layer itself.
I have a different dataset that has a view layer, and I tested that view layer and it is working on that one, so I don't know what to do next to troubleshoot.
