Hello,

I have a Nintex Workflow Query action that fetches 3 approver accounts from a row that has the requested authentication group name. It should then set 3 Workflow Person or Group variables to the 3 accounts found by the query, but the workflow keeps getting suspended with the error "An unhandled exception occurred during the execution of the workflow instance. Exception details: System.InvalidCastException:  The value 'Approver|Namee0]' cannot be read as type 'String'. ".

I want the query to find the 3 People or Group within the SharePoint list, then set those people to a People or Group Workflow variable. Is this possible? 
Note: In the error message above, I set the query column property to Account. 

Any guidance on how to accomplish this task would be immensely helpful!
