We have a SharePoint Server 2019 on premises.
We installed and configured Nintex for SharePoint and have applied the latest update putting us on Forms version 5.1.0.10 and Worflow version 5.1.0.0.
Some lists, not all, throw an error when loading the Forms editor. All we can get from the popup is the top of the HTML including the <head>. Nothing useful other than the <title>Request Error</title>.
The Form Controls and Ribon load, however, the Form never does.
Some info about when this happens. When a list is created and the columns are changed. When a list is migrated using ShareGate w/Nintex plugins.
I've included a screen capture.
Thanks in advance,
Bill
