Problem/Motivation

I get the following error when a content it's created or I'm clearing the cache, but only sometimes and Drupal shows me "The website encountered an unexpected error. Please try again later."

This is the error: "Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.path_alias.collection" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 208 of /code/web/core/lib/Drupal/Core/Routing/RouteProvider.php)"

I'm able to fix it with a new clear cache and I'm able to reproduce it only on one environment.

I'm using Drupal 8.9.10 and PathAuto 1.8

I have the tables path_alias and path_alias_revision in DB and in Drupal are no db updates available.

Steps to reproduce

It's really random. By creating content or by clearing the cache and only sometimes it shows the error.

Hello,

I confirm this issue. It's displaying really randomly and only on one environment.
I'm using Drupal 9.2.11, Pathauto 1.8.

Uncaught PHP Exception Symfony\Component\Routing\Exception\RouteNotFoundException: "Route "entity.path_alias.collection" does not exist." at /docroot/core/lib/Drupal/Core/Routing/RouteProvider.php line 206

Hello @andreiq

I could reproduce this issue with dblog module, it's just an example.

STR:
1) Just uninstalled the dblog module from UI here /admin/modules/uninstall
2) Then open any menu /admin/structure/menu/manage/[menu-name] and I see an error:
Uncaught PHP Exception Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException: "The "menu" entity type did not specify a "edit" form class." at /core/lib/Drupal/Core/Entity/EntityTypeManager.php line 211
3) Then click to Flush views cache on another admin page (Flush all caches > Flush views cache via admin menu).
4) After #3 I can see the error:
Uncaught PHP Exception Symfony\Component\Routing\Exception\RouteNotFoundException: "Route "entity.path_alias.collection" does not exist." at /core/lib/Drupal/Core/Routing/RouteProvider.php line 206

Why does it happen?
After #3, a lot of items were removed from router table from the database. You have to launch drush cr twice to fix such error.

Solution:
I Just applied this patch https://www.drupal.org/project/drupal/issues/3207813#comment-14380171

Hope it can help you.

Andriy.

I don't think there's anything this module an do about, sounds indeed like an imcomplete module list situation.
