No Receiver found

Hi Experts,

I am working on single sender to two receivers scenario. Sender side payload will be in below format.

-<Update>

    -<Target>

          -<Field1>

          -<Field2>

   -<Footer>

          -<Filed1>

If Target node exist then send the payload to Receiver-1,  if not exists then send the payload to Receiver-2. In Message mapping i gave the 1:2 transformation properly. In Receiver Determination i have given the conditions like below :

(/Update_/Target EX ) to send the message to Receiver-1

(/Update_/[not(Target)] EX )  to send the message to Receiver-2.

but when i am triggering the payload getting "No Receiver could be determined" error.

Please help on this.

Thanks
