Firmware update failed (NoneType object is not iterable)
When I try to update my lopy (not lopy4), I get the following error message:
I flash from local file (1.18.2.tar.gz), I've updated ~30 devices successfully and this is the first time I see this error.

If I select the newest stable firmware, i.e. not flash from local file, I am able to update the firmware.
The older firmware is downloaded from here: https://software.pycom.io/downloads/LoPy.html
As I have already mentioned, I have updated 30+ devices, flashing from local file and only this particular device is giving me problem.
