[node.latest_version_tab] Plugin doesn't exists error

Hi @gaurav_manerkar, can you add a full stacktrace of the error? That would be really helpful context for diagnosing this.

Thanks!

@gaurav_manerkar The output you posted in #3 is the full error, but it is not a stack trace.

I was unable to reproduce this. If you can provide a full error with backtrace by changing the logging settings to 'full error with backtrace' - please re-open.

I just got the same error in Drupal 8.9.11, a week after upgrading from 8.9.6. Rebuilding caches cleared it out. Hopefully, this will not happen often.

Can confirm getting similar errors on drupal 8.9.13, clearing cache does resolve the issue, but really would like to know the cause. This is affecting more than just one module.

It looks like we are still waiting for a trace.

Actually @emb03 you are reporting a different missing plugin.

This issue is about content moderation and awaits a stack trace.

I've got the same issue with a drupal 10 site and I can't quite pin this down- these random WSODs are driving me nuts. This error was logged for a page where there was no "latest version". While we do have moderation and workflows enabled- the particular page where this error was logged did not have an unpublished revision at the time. So I'm not sure why the latest_version_tab plugin was needed for this page in question. Is it possible that this might be ab issue with the local task manager or twig cache? here's a call stack:

This might be related to https://www.drupal.org/project/drupal/issues/3056633, it's a drupal 9 to drupal 10 upgrade issue where "plugin not found" exceptions are triggered, there are various causes so it's more like a megathread for a common symptom that might have numerous causes.

It is reproducible. Not always but it occurs at least once in 24 hours if you do lots of content entries.

I have added a check to confirm only check latest_version_tab if its available.

Will need an issue summary update and test case.

Sadly this issue keeps happening even with that patch. Does anyone have some deeper knowledge on the plugin discovery process (I don't have a lot of knowledge in that area)? I wonder if the "plugin not found" part is correct, because the "latest version tab" is NOT supposed to be rendered on the pages we're seeing this error. So why does it expect to find the plugin when attempting to render the local task block? Then there's the permission issue where it's trying to render the local task block with the "latest version tab" to anonymous users, who don't have permission to see it.

We regularly face the same issue:

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "views_view:view.block_content.page_1" plugin does not exist. Valid plugin IDs for Drupal\Core\Menu\LocalTaskManager are: [long list here including some other views_view:view.... tabs].

Another one here running into the same issue. Clearing the cache works each time, but some days this error occurs multiple times, making it annoying.

I'm currently on Drupal 10.4.5

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "views_view:view.block_content.page_1" plugin does not exist.
Valid plugin IDs for Drupal\Core\Menu\LocalTaskManager are: <huge list> in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 53 of /web/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php).

We are experiencing the same issue on Drupal 10.6.2. The problem occurs intermittently, and clearing the cache resolves it temporarily.

I encountered the same issue on 10.5.8, and clearing the cache solved it too. But a don't use Content moderation on this site.
