Automating Automation - Journal file could not be run to completion

I have once again the same problem.

Journal file could not be run to completion
And the graph is not executed.

I’ve tried with my own script and with Scenario_A1_2017 (changing my version to 2018)
I’m pretty sure that I meet the requierements.

Anyone knows where does that error come from? What can I try to solve it?
