The expression ImplicitReturnNode returns the type null which is incompatible with the return type mandated by Yiisoft\Queue\Adapter\AdapterInterface::push() of Yiisoft\Queue\Message\MessageInterface.

The method setId() does not exist on Yiisoft\Queue\Message\MessageInterface. It seems like you code against a sub-type of Yiisoft\Queue\Message\MessageInterface such as Yiisoft\Queue\Message\IdEnvelope.
