Circular reference detected for service

This sounds like an edge case that may never occur ever again. Would you be OK if we closed this one as "Won't fix"?

FYI: We're running into the same error with random modules, I think this doesn't mean it's casued bei ECA, might be a core bug since 10.1.x. Never experienced this before.

@Anybody can you please provide more details? The original issue is about business_rules, I'd like to understand which other modules you've seen with similar issues. And if so, are they only showing those issues in Drupal 10.1 and not in 10.0?

@jurgenhaas in our case it was: 🐛 Circular reference detected for service symfony mailer config override in multilingual sites Fixed
As symfony_mailer is very widely used now, I think that may be the reason in most cases.

Thanks @Anybody for the link to the other issue. Don't see any relation to ECA in that one. Do you have any circular dependency issues which involve ECA services?

@jurgenhaas sorry I think my comment was confusing. It was just the same error message, so I wanted to let you know here in #3 that ECO might *NOT* be causing this, someone just thought that, as the error appears when uninstalling *unrelated* modules (like propably ECA in that case or in our case reroute_email).

I'll close this cannot reproduce as unrelated to the module that was uninstalled so.

In case anyone lands in this issue before Circular reference detected for service 💬 Circular reference detected for service Active . I applied the patch provided on that issue and it fixed the circular reference problem.
