尝试通过 PayPal API 上传文件证据时获取 INVALID_REQUEST-MISSING_OR_INVALID_REQUEST_BODY

Question

我正在尝试通过 PayPal API (https://developer.paypal.com/docs/api/customer-disputes/v1/) 的文档上传证据文件

但我收到错误 400 - INVALID_REQUEST, MISSING_OR_INVALID_REQUEST_BODY。

我不明白我做错了什么。这是生成表单数据的代码的一部分：

const str = {
evidences: [
{
evidence_type: "PROOF_OF_FULFILLMENT",
evidence_info: {
tracking_info: [
{
carrier_name: "FEDEX",
tracking_number: "122533485"
}
]
},
notes: "Test"
}
]
}
const data = JSON.stringify(str);

const formData = new FormData();
formData.append('input', data);
formData.append('type', "application/json");
formData.append('file1', fileBuffer, {
filename: "@maor.pdf"
});

这是请求的日志：

您正在发布表单数据。 PayPal REST API 不接受表单数据，仅接受 JSON 字符串，对于此特定调用，该字符串必须是多类型内容字符串的一部分。请参阅您链接到的文档以了解该字符串的外观；从您的日志中可以清楚地看出，您没有发布这样的字符串。
