SonataUserBundle Api Response returns empty JSON

Question

I'm trying to get the JSON response of SonataUserBundle Api. So after following the config process from the Sonata HomePage docs

It looks like this API returns an empty object

It looks like you forgot to add metadata directory to jms_serializer config.

jms_serializer:
    metadata:
        directories:            
            SonataDatagridBundle:
                namespace_prefix: 'Sonata\DatagridBundle\'
                path: '@SonataDatagridBundle/Resources/config/serializer'

            # Also don't forget to add NewsBundle metadata too
            ApplicationSonataNewsBundle:
                namespace_prefix: 'Application\Sonata\NewsBundle\'
                path: '@ApplicationSonataNewsBundle/Resources/config/serializer'
