Python Django LineBot Error 54 'Connection reset by peer' - python-3.x

Question

I'm trying to crete linebot through python Django, I want to send some messages and let it scrape the website. Since there is form on the website, I use post request to send the form.
Although I scrape the data successfully, there is error message showed in the python. It seems linebot occupy post method in Django and I send another post request again. I'm not sure my understanding is correct. I can't find any solution about this. Could someone teach me how to fix it?
Exception happened during processing of request from ('127.0.0.1', 50246)
Traceback (most recent call last):

ConnectionResetError: [Errno 54] Connection reset by peer
Below is my code, I receive some keyword and post request to website. Finally, reply to user
#csrf_exempt
def callback(request):
if request.method == 'POST':
signature = request.META['HTTP_X_LINE_SIGNATURE']
body = request.body.decode('utf-8')
content = "None"
try:
events = parser.parse(body, signature)
except InvalidSignatureError:
return HttpResponseForbidden()
except LineBotApiError:
return HttpResponseBadRequest()
for event in events:
if isinstance(event, MessageEvent):
msg = event.message.text.strip()
if msg.startswith('!'):
msg = msg.replace('!', '')
if msg == 'temp':
content = "HELP"
elif msg.startswith(' '):
content = 'Command not found'
elif ' ' in msg:
info = msg.split(' ')
if len(info) > 2:
content = 'Too many arguments'
else:
ID = info[1]
temp = temperature.TempReport(ID)
content = temp.scrape()
#content = 'Test'
else:
content = 'Unknown command'
line_bot_api.reply_message(
event.reply_token,
TextSendMessage(text=content)
)
print('submit success')
else:
line_bot_api.reply_message(
event.reply_token,
TextSendMessage(text=msg)
)
return HttpResponse()
else:
return HttpResponseBadRequest()
Here is scrape code
def scrape(self):
if not self.postToServer():
return f'ID:{self.ID} submit temperature fail!'
return f'ID:{self.ID} submit temperature successfully
def postToServer(self):
self.session.post(self.url_in, data=self.payload)
sleep(0.1)
resp = self.session.get(self.url_out)
sleep(0.1)
soup = BeautifulSoup(resp.text, features='lxml')
result = soup.find(class_='title-text').text.strip()
return 0 if not 'completed' in result else
The post request work fine and the error happened when I return HttpResponse in callback function. I don't know what is the issue here...
