            I am not familiar with this specific connector, but one possible explanation is a compatibility issue between the connector version and the kafka connect worker version.

            You need to check out the connector's documentation and verify which version of connect it supports.

            Is "Tab Pages" a Content Type in your filter?

            Have you tried running the Update Database job and clearing Drupal's cache?

            If that doesn't sort it out. I would then try installing the Twig Tweak Module. Then locate the server folder of the theme in use at: /web/themes/custom/...

            Inside there, it seems you might have a custom template utilizing the Twig function:

            How to ensure composite commands including persisting to db and dispatching events are atomic?

            "Outbox Pattern": write the events to the database as part of the transaction; worry about publishing the events separately.

            See Reliable Messaging without Distributed Transactions, by Udi Dahan

            Either everything is persisted and all events are dispatched or nothing is persisted and no events are dispatched.

            Because we have physical constraints (ex: a finite speed of light), all or nothing isn't a guarantee that we can make. We can manage weaker claims, like "at most once" or "at least once".

            "At least once" is the weaker claim that is actually useful, but it does mean that subscribers have to be able to recognize repeat messages - in other words, you need idempotent message handling.

            EasyCorp\Bundle\EasyAdminBundle\Event\BeforeEntityPersistedEvent:class is not proper Symfony event name. You probably should use Doctrine\ORM\Events::prePersist.

            Also please check your DoctrineBundle version. If you're using the default services.yaml configuration and DoctrineBundle lower than 2.1, you have to configure services.yaml with:

            I'd like to encode a given class of type T: EventData with Kotlinx Serialization encodeToString.

            This is my code:

            ...

            ANSWER

            Answered 2021-Dec-08 at 14:39

            For Json.encodeToString(event) to work, it needs the type information for T. But, this type information is lost at runtime due to the way how generics work in Kotlin/Java.

            One way to retain the type information would be by making dispatchEvent an inline function with T as a reified type parameter.

            However, this also raises the question how you want to serialize event. You could also use polymorphic serialization of EventData, rather than trying to serialize T. This will include an additional class discriminator in your serialized output (it necessarily has to for polymorphic serialization/deserialization to work).

            If you serialize the concrete type T, this class discriminator wouldn't be included, which is questionable; how would whoever will deserialize this know what type it is?

            In short, I think you need polymorphic serialization.
