Showing browser in modal causes javascript error

This is most likely related to the deprecation of jquery.once, and should be replaced with core/once, according to https://www.drupal.org/node/3158256 →

Patch created

The issue is not related with jquery.once, it is caused by an undefined array key.

Logs info:
Warning: Undefined array key "" in Drupal\layout_builder_browser\Form\BlockForm->form() (line 101 /var/www/html/web/modules/contrib/layout_builder_browser/src/Form/BlockForm.php)

It's caused by commit https://git.drupalcode.org/project/layout_builder_browser/-/commit/10620... in src/Form/BlockForm.php, if we revert the changes in that file modal works as expected.

I'm so sorry, I misunderstood your message.

There's another issue when adding a new block to a block category using the Place Block button in Layout Builder Browser settings, but is not related to this one.

Thanks @mccauslt for reporting and pointing the direction for the fix. Thanks @Abil_Siddiqui for the patch. I applied and it fixes the error in the console. However, the modal still not close. I will mark this ticket as solved given the error in the console is fixed and create a new one for the modal not closing. I will try to reinstall a Drupal 9 version to see if the modal was closing earlier and if it is a bug introduced during the Drupal 10 compatibility.

Automatically closed - issue fixed for 2 weeks with no activity.
