elasticsearch - ElasticSearch: “Object field starting or ending with a [.] makes object resolution ambiguous: []”

Question

我收到错误“对象字段以[。]开头或结尾使对象分辨率模糊:[]”。但是我的对象中没有单个点[。]。我使用elasticClient.update()通过:

{

    "type": "applicant",

                        "endDate": null
                    },
                    "address": {
                        "street": null,
                        "city": null,
                        "state": null,
                        "zip": null
                    }
                }],
                "agencies": [{
                    "": {},
                    "agencyName": null,
                    "backgroundInvestigator": null,
                    "contactNumber": null,
                    "extension": null,
                    "position": null,
                    "email": null,
                    "stepsCompleted": null,
                    "dateApplied": null,
                    "status": null,
                    "address": {
                        "street": null,
                        "city": null,
                        "state": null,
                        "zip": null
                    }
                }],
                "disciplined": {
                    "response": false,
                    "explanation": ""
                },
                "warnedDrugs": {
                    "response": false,
                    "explanation": ""
                },
                "valid": true
            }
        }
    }
}

我已经看过几次了。我认为错误消息不足。 “对象分辨率不明确:[]”似乎暗示我有一个空数组，但没有。

Answer 1

json的值可以为空。但是，如果键为空，则ES在索引时会引发错误。
从json中删除"":{}并再次索引。
