String Fully qualified name of the last service (that is, most recently called) on the call stack.

String Path representing the last executed flow step in the service where the exception occurred. The path takes the form /n/n/n..., where n represents a sequential index of flow steps and / indicates a level of nesting. The following illustrates an example of flow steps and the flowStep value that would be assigned to them if the exception occurred at that step:

If the stack contains a Java service, the flowStep value for that service will be empty.
