[Udemy] AttributeError: 'NoneType' object has no attribute 'copy' error while downloading a course

[LionelFernandez]

I am downloading a course from Udemy using the command
C:\Users\Udemy>youtube-dl --verbose -u 888888@gmail.com -p ******** --ignore-errors --cookies "C:\Users\Udemy\Videos\UdemyVideos\login.json" -o "Videos/udemyvideos/%(playlist)s/%(chapter_number)s - %(chapter)s/%(title)s.%(ext)s" --ignore-errors --batch-file "C:\Users\Udemy\Videos\udemyVideos\MyURL.txt"

This happened with a number of courses

It is proceeding well; but at one of the lecture, I am facing an error and the scripts stops even though i put in the parameter --ignore-errors
