Amazon SP API：Feeds API 處理報告神秘錯誤代碼和消息

Question

我目前正在構建一個 API，允許用戶以編程方式在他們的亞馬遜賣家賬戶中列出產品。 我已經能夠實施 OAuth 流程、進行 API 調用的簽名機制，並完成了 Feeds API 用例指南中提供的推薦步驟。 最后一步是審查提要 API 處理和報告，這是我處於死胡同的地方。 解密和解壓縮響應后，我得到一個 JSON 有效負載，如下所示。 但是，我無法理解錯誤，以及如何根據顯示的錯誤代碼和消息糾正它：

{
  "header": {
    "sellerId": "A1HGLY0OQBKE5U",
    "version": "2.0",
    "feedId": "50021018827"
  },
  "issues": [
    {
      "messageId": 1,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 2,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 3,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 4,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 5,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 6,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 7,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 8,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 9,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    },
    {
      "messageId": 10,
      "code": "4002008",
      "severity": "ERROR",
      "message": "The provided message did not meet the schema validation requirements for a feed message."
    }
  ],
  "summary": {
    "errors": 10,
    "warnings": 0,
    "messagesProcessed": 10,
    "messagesAccepted": 0,
    "messagesInvalid": 10
  }
}

最初上傳的 json 負載基於此處提供的JSON_LISTINGS_FEED提要類型架構

加密前的確切負載如下所示：

{
  "header": {
    "sellerId": "A1HGLY0OQBKE5U",
    "version": "2.0"
  },
  "messages": [
    {
      "messageId": 1,
      "operationType": "UPDATE",
      "sku": "sk129"
    },
    {
      "messageId": 2,
      "operationType": "UPDATE",
      "sku": "sk1005"
    },
    {
      "messageId": 3,
      "operationType": "UPDATE",
      "sku": "sk131"
    },
    {
      "messageId": 4,
      "operationType": "UPDATE",
      "sku": "sk132"
    },
    {
      "messageId": 5,
      "operationType": "UPDATE",
      "sku": "sk133"
    },
    {
      "messageId": 6,
      "operationType": "UPDATE",
      "sku": "sk134"
    },
    {
      "messageId": 7,
      "operationType": "UPDATE",
      "sku": "sk135"
    },
    {
      "messageId": 8,
      "operationType": "UPDATE",
      "sku": "sk136"
    },
    {
      "messageId": 9,
      "operationType": "UPDATE",
      "sku": "sk137"
    },
    {
      "messageId": 10,
      "operationType": "UPDATE",
      "sku": "sk138"
    }
  ]
}

終於找出錯誤所在。 使用在線 JSON 模式驗證器工具。 並根據此架構對其進行驗證並相應地調整您的有效負載。
