Undefined array key for non-reusable blocks

Hello yugro, I have followed given reproduced step but not got any error so please provide proper reproduced step as well.
my configuration drupal -9.5.10

Hello shiv_yadav, I think I found the issue, it was that we had reusable value == 0 in block_content_field_data table and such blocks were cropped by getBlockTypeByUuid() function in EntityViewModeRestriction.php. Though in the same file there is an expression $delta = $content_block_types_by_uuid[$uuid]; , where $uuid includes all blocks in DB and $content_block_types_by_uuid includes only those with reusable==1. I have updated DB for the value and it works. But perhaps it would be good to have check if $uuid is in_array();

Hello @yugro,
As i have made changes as per your requirements in the code in file EntityViewModeRestriction.php . Also created MR for this . Kindly review the changes .

Thank you.

Hi @shiv_yadav,
Unfortunately I am not a maintainer or the module to review MR.

Thanks for responding, take clone this MR on local. verify your issue.it's fixed or not.

I might have been unclear on the steps to reproduce. I enabled layout builder and layout builder restrictions for basic page on vanilla Drupal 10.1.5. I added one reusable and one inline Basic block to a node. Then I created a custom block type and added one reusable and one inline instance of the custom block to the node. I could not reproduce the error.

Based on the comment in #10 above, I'm going to mark this as "Postponed (Maintainer needs more info)." We need specific steps to reproduce. Thanks!
