Migration from Moodle to Open edX platform

Hello everyone!

Does anyone use this module for converting moodle courses into edx courses? →

When I run the script I get this error:

Converting moodle intro_to_stats.mbz to edX content-univx-course

tar: Child returned status 2
tar: Error is not recoverable: exiting now

Thank you in advance.
