Circular reference detected for service "theme_handler" on cache clear

This is not the configuration system. The dependency injection container does not allow circular object dependencies. Can you explain a little more what you are asking?

We are using this https://www.drupal.org/docs/drupal-apis/configuration-api/configuration-... → to override the theme logo. But to find the active theme, we need "theme.manager" service which we have included from here https://git.drupalcode.org/project/high_contrast/-/blob/8.x-1.x/high_con... Now clearing cache gives this "Circular reference detected for service" error. To solve it, we are planning to remove the dependency injection and use the service directly:

$theme = $this->themeManager->getActiveTheme()->getName();
-->
$theme = \Drupal::theme()->getActiveTheme()->getName();

Shorten title, moved full message to the Issue Summary.

What is “now” in “Up until now”? Did a specific Drupal release change a behavior?

No, I mean I've never had problems with dependency injections in D8 or D9. First time I learned about this problem was when users started to complain when using High Contrast module. Then again I have not used config.factory.override before.

I am closing this as there have been no replies. Reopen it if needed.
