When setting the node_label attribute in a job planner throws an error for Illegal key specified.

I have attached workflow_generator.py script that recreates this behavior.

Example planner error:
[1] java.lang.RuntimeException: Unsupported key nodeLabel for element jobs - {"type":"job","name":"namd","id":"ID0000001","nodeLabel":"namd_eq_200","arguments":["equilibrate_200.conf"],"uses":[
