Unable to add a video in a lesson (JavaScript error – course-v2)

Issue Description

Description

We are experiencing an issue when trying to add a video to a lesson.

This problem occurs on course-v2.

Instead of displaying the expected interface, the screen turns into a grey background, which most likely should contain a lightbox/modal. However, the lightbox does not appear and a JavaScript error is thrown instead.

  A lightbox/modal should open to allow video selection or upload.
