TypeError: Cannot read properties of undefined (reading 'querySelector')

Patch based on proposed solution.

Updated patch that actually works

I haven't been able to replicate this error on 2.0.8 or the latest 2.0.x branch. Can you provide more information on your configuration?

Just ran into exactly same issue. Tested patch #4, working for us.

Sorry, didn't mean to change that.
Tested 2.1.0, so far unable to reproduce the issue.

Hello, I encountered an issue while using multiple fields directly in a node with Layout Paragraphs in version 2.1.0. If there are multiple fields with Layout Paragraphs in a node, it only works correctly for elements in the first field. In each subsequent field with Layout Paragraphs, it does not function properly.

For me, the fix from patch #4 worked, but only the first part, and not in the file builder.es6.js, but in builder.js.

@ckng see https://www.drupal.org/project/layout_paragraphs/issues/3476838 🐛 JS error when Drag and Dropping Active for video demo of problem, not sure what exact conditions you have to have for the drag and drop to not work, but its only on some of our content pages not all.

Created a patch for 2.1.x branch, patch #4 could not apply for me, so use https://git.drupalcode.org/project/layout_paragraphs/-/merge_requests/18...

Here is a debugger on the issue for those interested

Ran into the issue again. Rerolled and rebased to 2.1.x. Generated patch.

I tested it in a Drupal 11 installation and the error is fixed by the patch #15. The "move up" and "move down" buttons are now removed from the keyboard navigation when only one item is present.
