我正在尝试将JSON发送到elasticSearch。我尝试使用Postman和SOAPUI数据是

[{"column1": "abc", "column2": "def", "column3": "dghi", "column4": "jkl", "column5": "mno"}, {"column1": "pqr", "column2": "stu", "column3": "vwx", "column4": "", "column5": ""}]

我回来了以下错误

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "failed to parse"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "failed to parse",
    "caused_by": {
      "type": "not_x_content_exception",
      "reason": "Compressor detection can only be called on some xcontent bytes or compressed xcontent bytes"
    }
  },
  "status": 400
}

但是当我发布单个JSON数组即

{"column1": "abc", "column2": "def", "column3": "dghi", "column4": "jkl", "column5": "mno"}

然后工作正常。我是ElasticSearch的新手，所以不确定出什么问题。
