Update Scenario simple.json

I'm trying new version (0.6.0) of lorhammer. When i launch the orchestrator with this command orchestrator -mqtt tcp://ADVERTISED_HOST:1884 -from-file "./resources/scenarios/simple.json"

unfortunately i have these erros:

I read in the changelog that you've changed the init section of json file. Is it possibile to update the tests scenario?
