Hello,

We are doing SharePoint 2013 to SharePoint 2019 migration stage wise. The site which goy migrated to SP 2019 contains Nintex workflow which query list action to get list item from another SharePoint site (currently resides in SP 2013 environment). 

I am getting below error while running the workflow,

The Web application at "http://siteurl" could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

Could anyone pls help if it will work or not?
