Hi @sd_md_rizwan

The exception message indicates a ‘System.NullReferenceException’ , which suggests that an object reference within the initialization of the global variables is not set to an instance of an object.

Looks like same issue faced by many people.

Delete the variable & re-create it again in Data Manager by giving the Default value.

Hope this helps :slight_smile:
