When trying to install display builder I get a wsod and the following error shows:

Error: Call to a member function getPath() on null in Drupal\config_translation\ConfigNamesMapper->getOverviewRoute() (line 248 of /var/www/html/web/core/modules/config_translation/src/ConfigNamesMapper.php).

Running xdebug the last two lines of code processed before the error is triggered are:

return $this->routes[$name] ?? null; (line 135 - vendor/symfony/routing/RouteCollection.php)
return $this->routeCollection->get($this->getBaseRouteName()); (line 206 - core/modules/config_translation/src/ConfigNamesMapper.php)

Where $name = 'entity.pattern_preset.edit_form'

The module is installed, but everytime I flush caches I then get the same error.

The backtrace from the error in the log is:

Thanks a lot Ben for your tickets. We are in late alpha phase and those feedbacks are very valuable.

I am not reproducing the issue. Can you tell us a bit more? It seems you were editing a pattern preset (/admin/structure/display-builder/preset/{preset}), created from where (page layout? entity view display?)? in original language or a translation?

Thanks Pierre for coming back on this so quickly. Having tested a bit further, it looks like this might be something to do with my site set up. I tested it on another simpler site and it installed fine.

I hadn't created or edited any pattern presets. I tried uninstalling the whole ui_suite (skins, patterns, styles etc) and then doing a drush install of display_builder, which pulled everything else in at the same time, but was still getting the same error.

I have a feeling it may be another contrib module I have installed that is causing the issue.

It turns out that the solution was to enable Display Builder UI in the modules list.

OK, i reproduce when I have config_translation module activated and display_builder_ui disabled:

 $ ddev drush pmu display_builder_ui
 [error]  Error: Call to a member function getPath() on null in Drupal\config_translation\ConfigNamesMapper->getOverviewRoute() (line 248 of /var/www/html/web/core/modules/config_translation/src/ConfigNamesMapper.php) #0 /var/www/html/web/core/modules/config_translation/src/Routing/RouteSubscriber.php(39): Drupal\config_translation\ConfigNamesMapper->getOverviewRoute()

Added to beta1 because it is a fatal.
