404从Microsoft Graph下载OneDrive内容

我正在尝试通过Microsoft API下载onedrive项的内容。但是，无论使用哪种方法，我都会得到404响应。这是python / requests中问题的再现

import requests
import json

root_url = "https://graph.microsoft.com"
base_path = "/v1.0/<tenant_id>/users/<principal_name>/drive/"

token = "ALONGTOKEN"

headers = {"Authorization": "Bearer %s" % token}

r = requests.get(root_url + base_path + "/root/children", headers=headers)
listing = json.loads(r.text)
target = listing["value"][0]
print("Target node:")
print(json.dumps(target))
print("Target node id:")
print(target["id"])

r = requests.get(root_url + base_path + "items/" + target["id"], headers=headers)
print("Target metadata:")
print(r.text)

resp = json.loads(r.text)
download_url = resp["@microsoft.graph.downloadUrl"]
print("Target download url:")
print(download_url)

r = requests.get(download_url, headers=headers)
print("Download response code:")
print(r.status_code)
print("Download response headers:")
print(r.headers)
print("Download response cookies:")
print(r.cookies)
print("Download response redirect history:")
print(r.history)

输出以下内容：

也就是说，尽管应该下载文件字节，但是紧随链接之后的结果却是404。我已经在Java，Python，bash / curl和浏览器中复制了此内容。任何人都可以帮助指出我在做什么错，或者这是Microsoft graph API的问题？

编辑：

我还可以使用此处描述的/ drive / items / {item-id} / content端点来复制相同的404 。对该端点的请求将导致302重定向（如文档中所述），当遵循该重定向时，将导致与上述相同的404行为。

编辑2：

这是我可以在响应标头中找到的所有请求ID，它们对于从Microsoft端进行调试似乎很有用。

对于商品对象上的200个请求：'request-id'：'adfa3492-4825-439d-8e59-022f32e78244'，'client-request-id'：'adfa3492-4825-439d-8e59-022f32e78244'

对于下载网址上的404请求：“ request-id”：“ 33e09e9d-b0c2-2000-133c-304585c15000”，“ SPRequestGuid”：“ 33e09e9d-b0c2-2000-133c-304585c15000”，

此外，从404返回的实际HTML包括相关性ID：a8e09e9d-a0bb-2000-133b-ef6fc8ac7015
