我对python有点陌生，我试图在django项目中使用一个序列化器类序列化的外部api，我得到以下错误

Traceback (most recent call last):
  File "lib/python3.8/site-packages/django/core/handlers/exception.py", line 47, in inner
    response = get_response(request)
  File "/python3.8/site-packages/django/core/handlers/base.py", line 181, in _get_response
 response = wrapped_callback(request, *callback_args,**callback_kwargs)
TypeError: __init__() takes 1 positional argument but 2 were given
 "GET /project/v1/mypath/ HTTP/1.1" 500 56241

请看下面我的观点

import requests as requests
from rest_framework import viewsets
from rest_framework.response import Response
from .config import *
from .serializer import *
BASE_URL = BASE_URL
ACCOUNT_URL = "{}/v2/account".format(BASE_URL)
ORDERS_URL = "{}/v2/orders".format(BASE_URL)
HEADERS = {'APCA-API-KEY-ID': API_KEY, 'APCA-API-SECRET-KEY': SECRET_KEY}
# Create your views here.
class AlpacaGetAccountView(viewsets.ModelViewSet):
    serializer_class = AlpacaAccountSerializer
    queryset = AlpacaAccount.objects.all()
    def get_account(self):
        r = requests.get(ACCOUNT_URL, headers=HEADERS)
        serializer = AlpacaAccountSerializer(r, many=True)
        return Response(serializer.data)
Honestly, I have no idea where the error is coming from
Please advise me on how I can resolve this and where the error is coming from

还有哪个 __init__() 错误是指什么？
编辑我编辑了问题中的代码@bdbd提出的建议现在只返回空数组（[]）
请告诉我如何实际获取数据
