reassembler.py lap error

[crackerben]

Tried several versions of all software, different captures, and get same error when trying to use lap in reassembler.py:

b@b-desktop:~$ reassembler.py -i output.parsed -m lap
Traceback (most recent call last):
File "/usr/src/iridium-toolkit/reassembler.py", line 88, in
zx=modes[config.mode]1
^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/src/iridium-toolkit/iridiumtk/reassembler/ida.py", line 1050, in init
outfile=open(config.output,"wb")
^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: expected str, bytes or os.PathLike object, not NoneType

Is this a bug or just user error? reassembler.py works fine with other modes.

Thanks
