“对象映射[价格]无法从批量Python上的嵌套更改为非嵌套”

Question

我正在尝试在ElasticSearch中插入一个文档，但每次我尝试在python中插入时，它都会返回一个错误。但如果我尝试从Kibana或cUrl插入，它的成功。 我已经尝试过elasticserach-dsl，但我也遇到了同样的错误。

（抱歉我的英语不好，我来自巴西：D）

我有错误：

elasticsearch.helpers.BulkIndexError: ((...)'status': 400, 'error': {'type': 
'illegal_argument_exception', 'reason': "object mapping [prices] can't be changed from nested to non-nested"}}}])

我的代码：

from elasticsearch import Elasticsearch
from elasticsearch.helpers import bulk
doc = [{
            "_index": "products",
            "_type": "test_products",
            "_source": {
                [...]
                "prices": {
                    "latest": {
                        "value": 89,
                        "when": 1502795602848
                    },
                    "old": [
                        {
                            "value": 0,
                            "when": 1502795602848
                        }
                    ]
                },
                "sizes": [
                    {
                        "name": "P",
                        "available": True
                    },
                    {
                        "name": "M",
                        "available": True
                    }
                ],
                "created": "2017-08-15T08:13:22.848284"
            }
        }]
        bulk(self.es, doc, index="products")

我的ES映射：
