"Executed steps should be referenced by step path instead of step name. Refer to getStep() method of the steps object in scripting help for details."
However, looking at the steps object in the web interface scripting help for get() shows:
"Get step object of specified name in current configuration hierarchy. Null will be returned if not found."
This does mention anything about a step path nor what the format of a step path is so that I can construct a hardcoded one.
