I have a problem with bean injections in Quarkus, for MongoClient.

I need a custom MongoClient with a custom Codec:

@ApplicationScoped
public class MongoClientProducer {

    String connectionString = "mongodb+srv://...";

    @Produces
    @MongoClientName("customClient")
    public MongoClient createMongoClient() {
        CodecRegistry codecRegistry = CodecRegistries.fromRegistries(
                CodecRegistries.fromCodecs(new CustomCodec()),
                MongoClientSettings.getDefaultCodecRegistry()
        );

        MongoClientSettings settings = MongoClientSettings.builder()
                .codecRegistry(codecRegistry)
                .applyConnectionString(new ConnectionString(connectionString))
                .build();

        return MongoClients.create(settings);
    }
}

Then I use it:

@ApplicationScoped
public class MyService implements SomeInterface{


    @Inject
    @MongoClientName("customClient")
    MongoClient customMongoClient;

    ...
}

And I get the following error:

jakarta.enterprise.inject.AmbiguousResolutionException: Ambiguous dependencies for type com.mongodb.client.MongoClient and qualifiers [@MongoClientName("customClient")]s>
        - injection target: com.myproject.MyService#customMongoClient
        - declared on CLASS bean [types=[com.myproject.SomeInterface, java.lang.Object, com.myproject.MyService], qualifiers=[@Default, @Any], target=com.myproject.MyService]
        - available beans:
                - PRODUCER METHOD bean [types=[java.lang.AutoCloseable, com.mongodb.client.MongoClient, java.io.Closeable, java.lang.Object], qualifiers=[@Any, @MongoClientName("customClient")], target=com.mongodb.client.MongoClient createMongoClient(), declaringBean=ccom.myproject.MongoClientProducer]
                - SYNTHETIC bean [types=[com.mongodb.client.MongoClient, java.lang.Object], qualifiers=[@Any, @Named("customClient"), @io.quarkus.mongodb.MongoClientName("customClient")], target=n/a]

I don’t understand why I got twice the bean with MongoClientName(“customClient”), in producer and synthetic.

I expect having only a single bean for my MongoClient.
I’ve tried to remove my mongo dependancies in the pom.xml, to see some of theme were redundant.
