I'm working with FOS Elastica bundle and trying to index some datas inside Elasticsearch.

I followed the doc so I wrote this conf

fos_elastica:
 clients:
 default: host: '%env(ELASTICSEARCH_HOST)%', port: '%env(ELASTICSEARCH_PORT)%' 
 indexes:
 app:
 index_name: app
 types:
 user:
 serializer:
 groups: [elastica]
 persistence:
 driver: orm
 model: AppBundleEntityUser
 provider: ~
 country:
 serializer:
 groups: [elastica]
 persistence:
 driver: orm
 model: AppBundleEntityCountry
 provider: ~

Then inside my entities I added the serialization group

use SymfonyComponentSerializerAnnotationGroups;
...

/**
 * @ORMTable
 * @ORMEntity
 */
class Country

 ...

 /**
 * @var string
 *
 * @Groups("elastica")
 *
 * @ORMColumn(type="string", length=64, unique=true)
 * @AssertNotBlank
 * @AssertLength(max=64)
 */
 private $name = '';

Then when I launch fos:elastica:populate everything is working well but all the field where I put the elastica serialization group are not indexed.

I'm using the Symfony serializer and folloewed the official docs but I don't understand and find why I fields are not indexed.

I tried to add

serializer:
 serializer: serializer

or

serializer: ~

But I get an error

Malformed action/metadata line [3], expected START_OBJECT but found [VALUE_STRING]

When I try without the serializer, everything is working well and all the defined field are indexed.

Did someone know how to fix this error ? Every issues I found on the FosElastica GitHub repo are related to the JMSSerializer.
