Python ValueError：尝试使用云函数中的字典更新Firestore文档时，一个或多个组件不是字符串或为空

我试图用我的python脚本创建一个Google Cloud函数，但我一直得到一个错误。尝试使用嵌套字典更新firestore文档中的字段时出错。下面是我的代码片段：

driverDB = driverDB = db.collection('drivers')
driverList = []
for doc in driverDB.get():
    driverList.append(doc.id)

for driver in range(0,len(driverList)):
    routeDataDict = {
       'route':routeByDriverDict[driver]
    }
   
    driverDB.document(driverList[driver]).update(routeDataDict)

我得到的错误是：

File "/layers/google.python.pip/pip/lib/python3.8/site-packages/google/cloud/firestore_v1/field_path.py", 
line 272, in __init__ raise ValueError(error) ValueError: One or more components is not a string or is empty.

RouteDataICT看起来像这样：

{'route': {'stop_1': {'name': 'Christa',
   'address': '742 Evergreen Terrace',
   'phone': 5555555555,
   'email': 'test@test.com',
   'has_reusables': False,
   'notes': None,
   'zone': 1,
   'leg_url': '',
   'seconds_until_arrival': 360.0,
   'completed': False,
   'num_containers_at_this_stop': 0},
  'url': 'https://www.google.com/maps/dir/39.74,15.0757',
  'pay': '$49.77',
  'partner': 'burger_hut',
  'date': datetime.datetime(2020, 11, 24, 1, 7, 1, 90282)}}

driverList[driver]正确地打印出文档ID的字符串，因此错误似乎在字典中

当我在jupyter笔记本上运行我的代码时，一切正常。当我在云函数中运行它时，我得到了上面的错误。当我将字典内部复制并硬编码到云函数的update命令中时，它就工作了。但是，当我将字典打印到云函数日志中，然后将其复制并粘贴到更新函数中时，它就不起作用了。云函数似乎发生了一些事情，把字典搞乱了

这是firestore上的数据（这是一条旧路线，目前在那里）

您确定

doc.id

不是整数吗？

---

如果它是一个整数，那么请尝试将其转换为字符串（

doc.id.toString（）

），因为firestore只接受key作为

string

或

null

错误发生前

driverList[driver]

的值到底是多少？您好@DougStevenson这是一个字符串，是文档id的名称。它是用户的UID。我已经通过向update命令传递一个简单的字典来测试了这一点，更新工作并更新firestore中的文档。似乎是嵌套字典的问题。那么，当您记录它时，它的确切值是什么？当我记录UID时，它是一些字符串，如“Lu2qHfOqtma48r7L2g4PsEDQizD2”，它属于str类。该字典与上面发布的字典类似。有趣的是，当我将jupyter笔记本中的字典复制并粘贴到云函数中时，它就起作用了。但是，当我将字典打印到我的谷歌云函数日志中，然后将其复制并粘贴到云函数的硬编码中时，它就不起作用了。谷歌云函数中出现了无法正确处理字典的情况。在jupyter笔记本中运行时，我的所有代码都运行得非常好。您能否像firestore上一样共享数据结构。

stop1

是地图吗？是，地图中包含字符。这是firebase身份验证UID字符串。我还通过一个简单的测试字典对它进行了测试，并且它进行了正确的更新
