SonataMediaBundle Custom Provider - php

Question

I'm trying to create two custom providers, one for PDF and another one for ZIP files.
This is my code.
services.yml
parameters:
application_sonata_media.zip_class: Application\Sonata\MediaBundle\Provider\ZipProvider
services:
sonata.media.provider.zip:
class: %application_sonata_media.zip_class%
tags:
- { name: sonata.media.provider }
arguments:
- sonata.media.provider.zip
- #sonata.media.filesystem.local
- #sonata.media.cdn.server
- #sonata.media.generator.default
- #sonata.media.thumbnail.format
- ['zip']
- ['application/zip']
sonata_media.yml
sonata_media:
contexts:
eag_zip:
download:
strategy: sonata.media.security.public_strategy
mode: http
providers:
- sonata.media.provider.zip
formats:
reference: { quality: 100 }
ZipProvider.php

When I push create and edit button, the file pass the validation, save in DDBB and file in server, but in URL /admin/sonata/media/media/233/edit?provider=sonata.media.provider.zip&context=eag_zip I get this Error message:
Unable to find template "" in SonataMediaBundle:MediaAdmin:edit.html.twig at line 48.
Trying to go to /admin/sonata/media/media/list?provider=sonata.media.provider.zip&context=eag_zip or /admin/sonata/media/media/list?context=eag_zip
Unable to find template "" in SonataMediaBundle:MediaAdmin:inner_row_media.html.twig at line 19.
I don't know to solve it.
any help would be welcome
thanks a lot
