I'm trying to install FOSElasticSearch bundle (using composer) into Symfony 3.2

}

When i change this line in composer.json file to install latest version

"friendsofsymfony/elastica-bundle": "5.*",

i get this error https://pastebin.com/CaYJYdFB

to

 "friendsofsymfony/elastica-bundle": "*",

then i get FOSElasticBundle version 4.1.2, but the problem with this version is when i try to populate it using

php bin/console fos:elastic:populate

i get this error

Content-Type header [application/x-www-form-urlencoded] is not supported 

People with same problem recommend upgrading to FosElasticBundle version 5.*.

fos_elastica:

clients: default: { host: localhost, port: 9200 } indexes: app: types: item: mappings: title: ~ author: ~ categories: ~ description: ~ tags: ~ location: ~

      persistence:
        driver: orm
        model: EBMB\BaseBundle\MediaItem\Model\Item
        provider: ~
        listener: ~
        finder: ~

Here is also my Elasticsearch configuration in config.yml
