Json NIFI我需要数组的信息，但只需要第一个信息

晚上好

我有一个具有以下值的JSON:

[
  {
    "oid_notas": 12750,
    "unidade": "BRYE",
    "nota_fiscal": "182477",
    "serie_nota_fiscal": null,
    "nota_fiscal_interno": null,

    "cep_origem": "37640000",
    "cep_destino": "36092005",
    "cnpj_transportadora": "34334442000196",
    "cnpj_destinatario": "17745613000150",
    "cnpj_unidade": "13143802000879",
    "placa": "EDP3H17",
    "data_inicio": "2023-12-18",
    "hora_inicio": "16:39:42",

    "cpf_motorista": "18407854620"
  },
  {
    "oid_notas": 12751,
    "unidade": "BRYE",
    "nota_fiscal": "182472",
    "serie_nota_fiscal": null,
    "nota_fiscal_interno": null,
    "data_nota": null,
    "embarque": "64167625",
    "cep_origem": "37640000",
    "cep_destino": "36092005",
    "cnpj_transportadora": "34334442000196",
    "cnpj_destinatario": "17745613000150",
    "cnpj_unidade": "13143802000879",

    "nome_motorista": "JORGE LUIS MASSEI",
    "cpf_motorista": "18407854620"
  }
]

实际上，我的Jolt变换:

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "cnpj_unidade": ["cnpjUnidade", "documentos[#2].cnpjEmissor", "remetente.cnpj"],
        "embarque": "numeroEmbarque",

        "cpf_motorista": "motoristas[#2].documento",
        "nome_motorista": "motoristas[#2].nome"
      }
    }
  },
  {
    "operation": "cardinality",
    "spec": {
      "cnpjUnidade": "ONE",
      "numeroEmbarque": "ONE",
      "cepOrigem": "ONE",

      },
      "remetente": {
        "cnpj": "ONE"
      },
      "transportadora": {
        "cnpj": "ONE"
      }
   }
 },
 {
    "operation": "default",
    "spec": {
      "calcularcarga": false,
      "documentos[]": {
        "*": {
          "tipoDocumento": 0
        }
      },
      "motoristas[]": {
        "*": {
          "tipoDocumento": 1
        }
      }
    }
 },
 {
    "operation": "modify-overwrite-beta",
    "spec": {
      "dataEmbarque": "=concat(@(1,data_inicio),' ',@(1,hora_inicio))",
      "dataEmissao": "=concat(@(1,data_inicio),' ',@(1,hora_inicio))",
      "dataPrevisaoFimEmbarque": "=concat(@(1,data_fim),' ',@(1,hora_fim))"
    }
 },
 {
    "operation": "remove",
    "spec": {
      "data_inicio": "",
      "hora_inicio": "",
      "data_fim": "",
      "hora_fim": ""
    }
 }
]

输出:

{
  "cnpjUnidade": "13143802000879",
  "documentos": [
    {
      "cnpjEmissor": "13143802000879",
      "chaveAcesso": "31231213143802000879550010001824771354201333",
      "tipoDocumento": 0
    },

      "chaveAcesso": "31231213143802000879550010001824721154911322",
      "tipoDocumento": 0
    }
  ],
  "remetente": {

  },
  "numeroEmbarque": "64167625",

    {

      "nome": "JORGE LUIS MASSEI",
      "tipoDocumento": 1
    },
    {
      "documento": "18407854620",
      "nome": "JORGE LUIS MASSEI",
      "tipoDocumento": 1
    }
  ],
  "calcularcarga": false,
  "dataEmbarque": "2023-12-18 16:39:42",
  "dataEmissao": "2023-12-18 16:39:42",
  "dataPrevisaoFimEmbarque": "2023-12-20 04:26:20"
}

栏中的信息:

"motoristas" : [ {
    "documento" : "18407854620",
    "nome" : "JORGE LUIS MASSEI",

我需要这个array-motoristas中的这个"documento"和"nome"-103.

在这次颠簸中，我只需要发送一次什么？

谢谢.
