Hi all,
I am trying to debug biztalk orchestration with no scope transaction set in it all are 'None' I executed the orchestration once and then open it in the debugger and set the breakpoint at the shape just after the Receive Now i reposted the message so the HAT shows the orchestration in 'Started' state i right clicked to go to the debugger view and tried to 'Attach' but i get the follwoing error.
The following error occurred when attaching to the instance:System.ArgumentNullException "No message was deserialized prior to calling the DispathChannelSink.Parameter Name : requestMsg

Anybody there who faced a similiar issue or point me out if i am doing anything wrong

TIA
