com.wm.app.b2b.client.ns.NSRuntimeException

I’m using wM 8.2 and I have a service that submits to TN, I try to step into the service but when it gets to built-in-service wm.tn:receive it throws this error: com.wm.app.b2b.client.ns.NSRuntimeException

Can anyone advice on what would be the problem.
Thanks

Yes some times step thru will get you that exception due to run time time out in the developer (this noticed in 712 also)…you need to trace/run thru fast:
