Description

How to reproduce?

  1. In the classic editor, create a post with a gallery with one image and save the post.
  2. Go to the media library and delete permanently this image.
  3. Go back editing the previous post. The gallery displays "No items found".
  4. Attempt to edit the gallery and check the browser console.

Here is the error displayed:

Uncaught TypeError: Cannot read property 'args' of undefined
    at n.<anonymous> (media-views.min.js?ver=5.8-alpha-50521:2)
    at f (underscore.min.js?ver=1.8.3:2)

and the trace:

  • Keywords needs-patch added

Thanks for the bug report, @Chouby.

Underscore library was updated in #45785. However, the error still persists.
I'm able to reproduce this error before and after the update.

  • Milestone changed from 5.8 to Future Release

With 5.8 Beta 1 next week and no patch/PR on this ticket, I'm going to punt this to Future Release. Once a patch/PR is available this ticket can be added back to a numbered milestone.
