Undefined array key "#active" in Drupal\admin_toolbar_tools\AdminToolbarToolsHelper->buildLocalTasksToolbar()

I have updated this issue in attached patch1, please review

Mohd's patch almost worked...

Added an is_array check prior to array_key_exists..

Can you provide more details on how to replicate this? I have yet to see this error on any of my sites.

I am too not geting this reproduced in local. In fact i wonder when i enable Enable/Disable local tasks display what are the changes would effect? As node edit and delete already there. (may somebody point here would help)

I was doing too much at the time to properly trace why the error was happening so I’m afraid this will be hard to replicate. I’m working with a very old site (all be it up
to date) and there is a lot going on in local tasks.

In general, I would say the if statement as it stands isn’t doing enough to ensure the integrity of the array. I guess this is why we are here?

Hi, We need more details here, I have tested this on Drupal- 10.2 versions & unable to reproduce this.

I run into this after installing content_entity_clone module on a site where admin_toolbar_tools is enabled and "Enable/Disable local tasks display" setting is turned on. Content entity clone uses hook_menu_local_tasks_alter() to create new local task but it doesn't define #active key. Fix is included in the MR for ✨ Admin content add link in operation Needs review . Unfortunately, I had trouble reproducing the issue. I'm getting it on a project with many contrib and custom modules but not on the clean Drupal install. Judging by the previous comments, issue is extremely rare but it may happen under very specific circumstances.
