Hi all,

I'm trying to implement some functionality in my CRM which is related to integration with SharePoint.
(I know about server-side integration, but customer doesn't want to have it)

I have a SharePoint 2013 on-prem version.

Here is a template of the link that I'm using:
sharepointsite/.../Upload.aspx

When the window opens I can see the desired window:

I can choose the file and click 'Ok'. But after when the spinner is appearing in the dev consol the error is throwing:

Uncaught TypeError: Cannot read properties of null (reading 'overrideDialogResult')
at gotoNextPage (Upload.aspx?List=.....)
at onload (Upload.aspx?List=.....)

Do you know how it could be resolved?
