[Quarkus]java.lang.IllegalStateException: No current Mutiny.Session found

Issue

I have some Panache Entity

@Entity
public class Test extends PanacheEntity {

    public String Order1;
    public String Order2;
    public String jiraKey;
    public String username;

}

And Resource where I want to transformt Uni into Multi

@Path("/api")
public class TestResource {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public Multi<Test> getAll() {

        Uni<List<Test>> orders = Test.<Test> listAll();

        return (Multi<Test>) orders.toMulti().flatMap(list -> Multi.createFrom().iterable(list));
    }
}
