ERROR: unpack requires a buffer of 2 bytes (HBC Version: 89)

Hi, I am trying to to reverse an APK which contains HBC Version 89, however I get the following error while it tries to unpack the instruction.hasm:

Traceback (most recent call last):

Same problem here, altough in my apk it's in "to_uint8"

Having the same issue here.
Did anyone find a fix for it?
