python3.5上的烧瓶发出请求错误。有什么问题吗？

在运行后端服务器时，出现以下错误

[25/Oct/2019 12:00:10] "OPTIONS / HTTP/1.1" 200 -
Error on request:
Traceback (most recent call last):
  File "/home/user/.local/lib/python3.5/site-packages/werkzeug/serving.py", line 304, in run_wsgi
    execute(self.server.app)
  File "/home/user/.local/lib/python3.5/site-packages/werkzeug/serving.py", line 297, in execute
    write(b"")
  File "/home/user/.local/lib/python3.5/site-packages/werkzeug/serving.py", line 276, in write
    self.wfile.write(data)
  File "/usr/lib/python3.5/socket.py", line 593, in write
    return self._sock.send(b)
  File "/usr/lib/python3.5/ssl.py", line 861, in send
    return self._sslobj.write(data)
  File "/usr/lib/python3.5/ssl.py", line 586, in write
    return self._sslobj.write(data)
ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:1848)

这也是烧瓶代码的开始

@app.route('/',methods=['GET','POST'])
def responseToExtensionRequest():
    if request.method == 'POST':
        requestString = request.get_json(force=True,silent=True) # read the request as json string

        global action_window
        # global goal_score

        requestGoal = requestString.get('goal')

这就是我所得到的全部错误。在我的代码中，它甚至没有显示出哪里出错了。网络中有代理吗？没有，我没有代理。你应该看看这里的答案。告诉我们你如何运行服务器，以及是否有任何服务器配置。
