$annotationReader is of type object<Doctrine\Common\Annotations\Reader>, but the property $annotationReader was declared to be of type object<Doctrine\Common\Annotations\AnnotationReader>. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?
