Find keyword name (or keyword name stack) in Robot Framework

I've been struggling with the same problem as in this question: Robot Framework location and name of keyword - i need to find a keyword name stack.
Seems like the author has found the solution.
Unfortunately, I cannot apply it because in my version of Robot Framework (3.0.2) object _ExecutionContext has no field or property keywords, so in my case the line EXECUTION_CONTEXTS.current.keywords[-1].name
raises an exception. Thank you for any help!
