PHP warning for inline Block layout Builder

There is not a call to that function on line 259 of that file in Drupal 10.4. How do we reproduce this bug?

That line doesn't match in 11.x either. Can you please check if you have other core patches applied to the site? If so, one of the patches could be causing this.

Drupal version is 10.5.1

There is not a call to function id on line 259 of core/modules/layout_builder/src/Plugin/Block/InlineBlock.php in Drupal 10.5.1. Comment #3 above is probably something you should look into.
