Additional info if applicable

Occurs sporadically when running the job-launch script. I don't have a consistent way to reproduce the error.

What branch of PythonMonkey were you developing on? (If applicable)

No response

@YarnSaw Can you repro to see if it has been fixed by https://github.com/Distributive-Network/PythonMonkey/pull/323?

[philippedistributive]

@Xmader I'm not sure he could repro even before your fix :-)

[YarnSaw]

Yeah, I never had a consistent repro for this. It happened probably 1 in 15 runs of deploying a job.

[philippedistributive]

and that was a month ago or so, no repro in 100s of runs since then

[Xmader]

I think we are good to close this issue.
