python - __call__() 缺少 1 个必需的位置参数：App Engine 上的“发送”FastAPI

Question

尝试在 App Engine 上托管 API 时，不断出现以下错误。该程序曾经在 Flask 上运行，该程序可以运行但速度很慢。

错误：

"Traceback (most recent call last):
  File "/env/lib/python3.7/site-packages/gunicorn/workers/sync.py", line 134, in handle
    self.handle_request(listener, req, client, addr)
  File "/env/lib/python3.7/site-packages/gunicorn/workers/sync.py", line 175, in handle_request
    respiter = self.wsgi(environ, resp.start_response)
TypeError: __call__() missing 1 required positional argument: 'send'
"
