.imscc to common cartridge issue

[bryansweeney]

Trying to convert a common cartridge exported from moodle (in .imscc format) to a Canvas common cartridge. When running through CLI

moodle2cc migrate ./ff1.imscc ./

Traceback (most recent call last):

I get the same issue when I try to do the same with a .zip extension for the cartridge file. This command works for small cartridges that are exported to the .mbz format from moodle.

I have verified that this is not related to the the path parameters that I am passing, because it works for .mbz file as explained above.
