quarkus: Postgres timestamptz not working with Hibernate reactive?

Describe the bug I have a column in the Postgres with type of “timestamptz”. However, trying to use these fields in the Hibernate always result in:

io.vertx.core.impl.NoStackTraceThrowable: Parameter at position[0] with class = [java.time.LocalDateTime] and value = [2020-07-16T10:10:24.378] can not be coerced to the expected class = [java.time.OffsetDateTime] for encoding.

It does not seem to matter what how I set the type. I have tried the following types: Date, LocalDateTime, OffsetDateTime and Date with @Temporal(TemporalType.TIMESTAMP). I have also tried with @CreationTimestamp, @PrePersist and the same with update methods also.

Always the same error, so the transformation to types happens outside my code and my classes seem to have no effect at all.

The code that does the persist:

    public Uni<Endpoint> createEndpoint(Endpoint endpoint) {
        return mutinySession.onItem().produceUni(session -> session.persist(endpoint))
                .onItem().produceUni(Mutiny.Session::flush)
                .onItem().apply(ignored -> endpoint)
                .onFailure().invoke(t -> {
                    System.out.printf("Failed to persist, %s\n", t.getMessage());
                });
    }

Expected behavior Timestamps should be persisted to Postgres.

Actual behavior Regardless of the type of property, the same error happens.

Environment (please complete the following information):
