Hyperledger Composer REST API出现“transactionId”：“string”

Question

将浏览器连接到Hyperledger Composer中的REST API时出现此问题。尝试发布tarnsaction时，它似乎是一个新字段，称为“transactionId”：“string”和“timestamp2：

{
  "$class": "org.cryptolab.economiassociales.AnadirNodo",
  "idNodo": "string",
  "nombre": "string",
  "localizacion": "string",
  "delegada": "string",
  "numeroMiembrosParticipantes": 0,
  "transactionId": "string",
  "timestamp": "2019-03-18T15:55:40.857Z"
}

尝试填充transactionId字符串，事务失败，出现422错误代码：

{
  "error": {
    "statusCode": 422,
    "name": "ValidationError",
    "message": "The `AnadirNodo` instance is not valid. Details: `transactionId` can't be set (value: \"s1\").",
    "details": {
      "context": "AnadirNodo",
      "codes": {
        "transactionId": [
          "absence"
        ]
      },
      "messages": {
        "transactionId": [
          "can't be set"
        ]
      }
    },

  }
}

它似乎与这个主题类似：transactionId when submitting a transaction

我能做什么？令人沮丧......

谢谢！
