流式处理firebase实时数据库时遇到问题

Question

当我尝试流式处理firebase实时数据库时，我收到一个类型错误。这是我的代码的MRE。我一直在完美地使用模块的其他功能，但由于某种原因，当我尝试流式传输数据时，这个错误不断出现

from firebase import Firebase
import python_jwt as jwt
from gcloud import storage
from sseclient import SSEClient
from Crypto.PublicKey import RSA
from requests_toolbelt.adapters import appengine

config = {
    "apiKey": "*******************************",
  "authDomain": "*********************************",
  "databaseURL": "*********************************",
  "storageBucket": "********************************"

}

pythonfirebase = Firebase(config)
db = pythonfirebase.database()

def stream_handler(message):
    print(message["event"])  # put
    print(message["path"])  # /-K7yGTTEp7O549EzTYtI
    print(message["data"])  # {'title': 'Pyrebase', "body": "etc..."}

my_stream = db.child("placements").stream(stream_handler)

这是完整的回溯

改用Firebase admin sdk进行尝试

import firebase_admin
from firebase_admin import credentials
from firebase_admin import db

# Fetch the service account key JSON file contents
cred = credentials.Certificate(SERVICE_ACCOUNT_FILE)

# Initialize the app with a service account, granting admin privileges
firebase_admin.initialize_app(cred, {
    'databaseURL': DATABASE_URL
})

# Get a database reference to our posts
ref = db.reference('messages')

def listener(event):
  print(event.event_type)  # can be 'put' or 'patch'
  print(event.path)  # relative to the reference, it seems
  print(event.data)  # new data at /reference/event.path. None if deleted

  node = str(event.path).split('/')[-2] #you can slice the path according to your requirement
  property = str(event.path).split('/')[-1]
  value = event.data
  if (node=='sala'):
  #do something
    """"""
  elif (node=='ventilacion'):
  #do something
    """"""
  else:
    """"""
#do something else

# Read the data at the posts reference (this is a blocking operation)
# print(ref.get())

db.reference('/').listen(listener)
