Media Library widget does not work inside LB

I cannot reproduce this in Drupal 10.1.

A similar Problem here:
Core: 10.1.4

Not sure if the error in the screenshot is related to this issue. Because I didn't find a useful pattern of the error. But when I clicked the "Add media" Button, nothing is happening besides the ajax loading gif.

I'm unable to replicate this issue on a fresh 11.x install of Drupal.

I've followed these steps:

1. Install a fresh Drupal 11 standard site
2. Enable Media, Media library & Layout Builder
3. Add Layout Builder and allow content item overrides to the article content type.
4. Add a media field to the basic block block type with the media library widget
5. Add media library to the basic_html text format
6. Create an article and go to Layout Builder
7. Add a basic block to the article. Verify that the media library opens correctly both in CKEditor & in the Media library field.

Since this can't be replicated I'm marking this as postponed. If you can replicate this with just core please update this with the steps. Thanks!

In d10.2.2 editing a block with layout builder and the media library widget in existing blocks I have the following error when trying to add a Media or select an existing one:

message: '\nAn AJAX HTTP error occurred.\nHTTP Result Code: 403\nDebugging information follows.\nPath: /media-library?destination=/node/8/layout&_wrapper_format=drupal_ajax&ajax_form=1&media_library_opener_id=media_library.opener.field_widget&media_library_allowed_types%5Bimage%5D=image&media_library_selected_type=image&media_library_remaining=1&media_library_opener_parameters%5Bfield_widget_id%5D=field_hc_image%3A-settings-block_form&media_library_opener_parameters%5Bentity_type_id%5D=block_content&media_library_opener_parameters%5Bbundle%5D=hotel_counters&media_library_opener_parameters%5Bfield_name%5D=field_hc_image&media_library_opener_parameters%5Bentity_id%5D=3329&media_library_opener_parameters%5Brevision_id%5D=28621&hash=R00G-VI2Jd-tylep7AkBs4y4KjJiYQYYbDpLcDZsRXk&views_display_id=widget\nStatusText: Forbidden\nResponseText: {"message":"Non-reusable blocks must set an access dependency for access control."}'

Without creating a new block it doesn't happen. Can somebody help me? I see that this error message comes from the checkAccess function in core/modules/block_content/src/BlockContentAccessControlHandler.php

I am having the same error:

When trying to use the media library insert button inside a block in layout builder.

Following up on my previous post. The error was due to the mini-pager view inside the gin_lb template. I made a patch to fix it. Hope it helps someone! https://www.drupal.org/project/gin_lb/issues/3461861 🐛 Media Library Widget broken when adding block in layout builder Active
