It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.

                'Calling the '.__METHOD__.' method with a Sonata\Doctrine\Model\ManagerInterface is deprecated'
                .' since version 2.4 and will be removed in 4.0.'

$tagManager is of type object<Sonata\Doctrine\Model\ManagerInterface>, but the property $tagManager was declared to be of type object<Sonata\ClassificationBundle\Model\TagManagerInterface>. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?
