Circular reference on multi-language sites

Thanks for the report. I was getting a lot of similar errors and I believe I fixed them with this commit. Please can you check if you still see the error with the latest dev version?

Should be fixed as described in #2. Please re-open if you still hit the bug with the latest release

Don't know exactly if this is the same issue, but when i am trying to enable the symfony_mailer module in its 1.x-dev version i get the following error:

www-data@9da9a3bd1635:/app$ drush en symfony_mailer

In Container.php line 147:

  Circular reference detected for service "language_manager", path: "language_request_subscriber -> language_manager -> config.factory -> plugin.manager.email_builder -> entity_type.manager -> string_translation -> strin
  g_translator.locale.lookup".


PHP Fatal error:  Uncaught Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException: Circular reference detected for service "entity_type.manager", path: "user_last_access_subscriber -> entity_type.manager -> string_translation -> string_translator.locale.lookup -> config.factory -> plugin.manager.email_builder". in /app/web/core/lib/Drupal/Component/DependencyInjection/Container.php:147

same problem as megadesk3000 on #5. After upgrading to 1.3.0-beta1, I can't add new modules if symfony_mailer is enabled, it cause a Circular reference detected error :

PHP Fatal error: Uncaught Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException: Circular reference detected for service "entity_type.manager", path: "user_last_access_subscriber -> entity_type.manager -> string_translation -> string_translator.locale.lookup -> config.factory -> plugin.manager.email_builder".

downgrading to 1.2.1 resolve the problem.

Thanks for the reports. It's not exactly the same issue, because it's no longer related to drush. The cause seems to be multi-language sites - which my test sites are not, so I don't hit it. Strange how each error message is slightly different from the others.

This was caused by #3315358: Allow full management of override plugins.

Probably the fix is something like this, partly undoing some changes in the above issue:

1. Create class MailerConfigOverride with tag config.factory.override, and remove that tag from EmailBuilderManager. Although this class uses EmailBuilderManager, it should not have it injected as that causes the loop.
2. MailerConfigOverride::loadOverrides() has a hard-coded test to ignore certain entries that are used during initialisation and would cause a loop, probably "core.extension", "symfony_mailer.settings" (see earlier patch that was later revised to the current code). Then it calls \Drupal::service('plugin.manager.email_builder')->loadOverrides().

Please can everyone seeing this bug please test this patch?

@AdamPS confirm #11 working for my DruStack, see https://github.com/drustack/composer-project-website-skeleton/commit/6dd...

Once patch applied and `drush -y cr`, site up and running once again, able to enable other else modules with no issue.

Thank you very much ;-)

Great thanks

I get same error but I can't apply the patch with dev and 1.3.0-rc1 version.
thank you

I met the same problem by installing 1.3.0-rc1 and running drush commands later.

Is the following issue related?
#3370109: Circular reference detected for service symfony mailer config override in multilingual sites

Same or similar issue here after upgrading to 1.3.0-rc1 on Drupal 9.5.10 and PHP 8.1.16

Circular reference detected for service "entity_type.manager", path: "scheduler.manager -> date.formatter -> entity_type.manager -> string_translat
