Webhooks causing FileNotFoundError

[BenCurtisD]

• gevent version: Pip installed, Version: 23.7.0
• Python version: Python 3.11.0 downloaded from python.org
• Operating System: Microsoft Windows Version 22H2 (OS Build 22521.1992)

Description:

I am trying to use webhooks from clickup to trigger python scripts using flask through gevent. The webhooks are clearly being received by the server, however instead of the desired functionality, I just get a gevent related error.

Traceback (most recent call last):

What I've run:

@app.route('/triggerauth')
def triggerAuth(methods=['POST']):
    return str(request.form)

from gevent import monkey
monkey.patch_all()

import sys
import gevent
from gevent.pywsgi import WSGIServer
from app import app, appInfo

new_env = {'GATEWAY_INTERFACE': 'CGI/1.1',
                'SERVER_SOFTWARE': 'gevent/%d.%d Python/%d.%d' % (gevent.version_info[:2] + sys.version_info[:2]),
                'SCRIPT_NAME': '',
                'wsgi.version': (1, 0),
                'wsgi.multithread': True, 
                'wsgi.multiprocess': True,
                'wsgi.run_once': False}

if appInfo["debug"]:
    http_server = WSGIServer(("0.0.0.0", appInfo["port"]), app, ssl_args='adhoc', environ=new_env)
    http_server.serve_forever()
else:
    http_server = WSGIServer(("0.0.0.0", appInfo["port"]), app, keyfile=appInfo["cert"] + '/privkey.pem', certfile=appInfo["cert"] + '/cert.pem', environ=new_env) 
    http_server.serve_forever()

Sorry in advance if I've made any errors with this issue report, I've never made one before.

I realize my actual code for detecting the webhook as it stands wouldn't help me know what I received but I will obviously change that as soon as I'm not having immediate gevent related errors.

The message pretty clearly seems to indicate that you're providing an SSL key or certificate (keyfile, certfile) that doesn't exist. Have you confirmed that the paths you're creating do in fact exist? (Also, be sure to use os.path.join() instead of string concatenation to form your path strings; you're on Windows --- which is only supported for development not production --- but using a POSIX separator; since the error is coming from the guts of OpenSSL, they may be expecting correctly-formed paths.)

I have made the changes for the path formatting, and it still has the same results. I know that the files are there because the server is already successfully working for browser use from outside connections. Only trying to use webhooks to this URL is causing errors.
