I have the following configurations: root/child-1/child-2/child-3
and in each, except for the last configuration, I created a step.
In Configuration "Child-1" i add the step from root and the step created in Child-1 to the workflow
In Configuration "Child-2" i added the step, created in this configuration, to the workflow.
in the last configuration "child-3" the workflow looks like:

master
  step-root
  step-1
  step-2

Based on the script above and here in the forum I wanted to create a list of the used steps of a configuration.
If I execute the script for the configuration root/child-1/child-2/child-3 only the step-root is listed.

16:09:43,897 WARN - Steps: master
16:09:43,897 WARN - Steps: step-root

Why are not all steps of the configuration shown?

sounds like master step of root/child-1/child-2/child-3 is overwritten or inherited incorrectly somewhere in your chain.

Looks like you are executing the script from a different configuration other than "root/child-1/child-2/child-3". The example script is updated to work in this case:

Thank you, that's exactly what I wanted.:thumbsup:
