KeyError: 'uint8_t[1169]' after `ulog.write_ulog(...)`

[Michał Barciś]

I have this snipped of code.

from pyulog import ULog
ulog = ULog("12_43_07.ulg")
ulog.write_ulog("/tmp/a.ulg")`

The file 12_43_07.ulg is a PX4 log generated using the code from the main branch of PX4

After executing the code above, the following exception is thrown and only partial data is saved in /tmp/a.ulg:
