Problem: Clicking Undo on the Edit widget in Web AppBuilder for ArcGIS causes the application to hang


While using the Edit widget to edit a hosted feature service in Web AppBuilder for ArcGIS, clicking the Undo button causes the application to hang and returns the following error.

SEVERE <date>, <time> An error occurred. <hosted feature service name>.MapServer


This issue occurs if a feature dataset contains m-values, and is a known limitation. For example, when edits are performed on a hosted feature service accessed by a platform that does not support editing m-values, such as ArcGIS Online or Portal for ArcGIS.

Solution or Workaround

There are two possible workarounds for this issue.
