It seems like array($consumers, $multiConsumers, $dynamicConsumers, $batchConsumers, $anonConsumers) of type array<integer,iterable> is incompatible with the declared type array<mixed,OldSound\RabbitMqBundle\RabbitMq\Consumer[]>|iterable of property $consumers.

It seems like $group can also be of type string[]; however, parameter $args of sprintf() does only seem to accept string, maybe add an additional type check?
