我正在尝试使用官方的javascript客户端创建一个带有Map的ElasticSearch索引。当我尝试在没有索引的情况下创建时，一切都很顺利，但在创建索引时，我遇到了一个错误。
下面是我的模式：

{
    "mappings":{
        "post":{
            "properties":{
                "city":{
                    "type": "text"
                },
                "contact_email":{
                    "type": "text"
                },
                "country":{
                    "type": "text"
                },
                "description":{
                    "type": "text"
                },
                "image":{
                    "type": "text"
                },
                "post_id":{
                    "type": "text"
                },
                "state_province":{
                    "type": "text"
                },
                "title":{
                    "type": "text"
                },
                "user_id":{
                    "type": "text"
                }
            }
        }
    }
}

当我执行上面的命令时，我得到这个错误：

    "error": {
        "root_cause": [

        }
