When you create a SharePoint Document Library with a Lookup required column, and you generate SmartObjects and Forms for the Document Library, uploading a document to SharePoint results in an error or not being able to select a value from the Lookup List.
The following error might occur: “No item exists. It may have been deleted or renamed by another user”.

- Install the K2 Five (5.2) May 2019 Cumulative Update FP6 to apply the fix.
