SharePoint 2013 error in the window with isdlg=1

Copper Contributor

Hi all,

I'm trying to implement some functionality in my site which is related to integration with SharePoint.

I have a SharePoint 2013 on-prem version.


Here is a template of the link that I'm using:

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?
