I have a transfomer service created in my process flow. There is no error when generating the deployment code and so on. But, when I run this process, the testing environment throws the follow error saying it can't resolve the partner link of this transformer service.

WSAD-IE debugger doesn't allow me to step into the generated transformer service code either. Anyone has any idea what went wrong?
