Critical <System> esa2-m.co: An application fault occurred: ('egg/command_client.py call

[alejandro.aguilar]

I started to receive this error message, 

An application fault occurred: ('egg/command_client.py call|242', "<type 'exceptions.TypeError'>", "'NoneType' object is not iterable", '[_coro.pyx coro._coro._wrap1 (coro/_coro.c:8505)|757] [updater/updaterd.py alert_autoupdate_disabled|1329] [shared/UpdateSupport.py __init__|538] [shared/UpdateSupport.py init_service_overview|547] [shared/UpdateSupport.py get_available_engine_updates|185] [egg/command_client.py call|242]')

I was looking online and  find a similar message related to a bug:

Version: 13.0.0-392

Someone have any idea what could be the root cause o this error message.

The defect suggests it could be potentially a network device interrupting the traffic towards the updater servers and resulting in the error.

I haven't seen it happen outside of that and no workarounds currently listed.

The alert is not known to impact working of the appliance currently.
