TI-API: orders/test 提示 ERR-TICOM-ORDER-API-00400

Part Number: TI-API

您好,测试transact.ti.com/.../test,已经填写了正确的checkoutProfileId及Authorization,请求的json里面只有checkoutProfileId的值,其他都是用的官网给的demo内容,但是执行之后会报错“ERR-TICOM-ORDER-API-00400”,json请求格式有问题吗还是别的什么原因?

我的请求json:
{
  "order": {
    "checkoutProfileId": "已设置",
    "customerPurchaseOrderNumber": "INSERT PO NUMBER HERE",
    "endCustomerCompanyName": "INSERT END CUSTOMER NAME HERE",
    "expediteShipping": false,
    "customerOrderComments": [
      {
        "message": "MY TEST ORDER"
      }
    ],
    "lineItems": [
      {
        "customerLineItemNumber": 1,
        "tiPartNumber": "NE555DR",
        "customerPartNumber": "MY CUSTOMER PARTNUMBER",
        "customReelIndicator": false,
        "quantity": 1,
        "customerItemComments": [
          {
            "message": "SOME COMMENT GOES HERE"
          }
        ]
      },
      {
        "customerLineItemNumber": 2,
        "tiPartNumber": "LM358PWR",
        "quantity": 1
      }
    ]
  }
}
返回结果:
{
    "errors": [
        {
            "errorCode": "ERR-TICOM-ORDER-API-00400",
            "section": "Generic",
