I've created a hosted Feature Layer with 22000 features. I then created a Hosted View to stop user from having editing access. While the view seems to have been created successfully I get the following error.
This is weird because I can open the view and access the rest end point. All the attribute information looks correct. I can even use the view successfully in a Web App.
If I log out of Portal and log back in a then go the the hosted view's item details I get the same error.
We're running ArcGIS Enterprise at 10.6.1. I can't see anything in the Server or Portal logs.
