graphql response in multiple languages ?

[kissa14]

Hello,

how to force graphql error message language?

exemple: 

{
    "data": {
        "customerUpdate": {
            "customer": null,
            "customerUserErrors": [
                {
                    "code": "TAKEN",
                    "field": [
                        "customer",
                        "email"
                    ],
                    "message": "Email has already been taken"
                }
            ]
        }
    }
}
