Purchase Order Error for quickbooks module

I have created a scenario, search google sheet module, if column= yes, then use search quickbooks vendor module (get vendor id) then use search quicksbooks item module (get item id) then i attempt to create a quickbooks purchase order (using vendor id and item id) no matter what combination i do i receive an error. (This logic path worked fine to create invoices)

I get this error (even though i have used the vendor id and tried using the actual dropdown list and selecting the supplier) (image of settings attached)

Validation failed for 1 parameter(s).

  • Missing value of required parameter ‘VendorRef’.
