Python 2.7.16 Gevent-socketio server throwing errors - python-2.7

Question

I'm currently trying to run some code from an old Github repo, and I'm running it on Python version 2.7.16, the code is ran from a file called server.py which starts a local web server where the app is run, code for that server.py file is as follows:
from gevent import monkey
monkey.patch_socket()
from flask import Flask, request, send_file
from socketio import socketio_manage
from resource import Resource
# Flask routes
app = Flask(__name__)
#app.route('/')
def index():
return send_file('static/index.html')
#app.route("/socket.io/<path:path>")
def run_socketio(path):
socketio_manage(request.environ, {'': Resource})
if __name__ == '__main__':
port_num = 8088
# port_num = 8000
# port_num = 80
print 'Listening on http://localhost:%d' % port_num
app.debug = True
import os
from werkzeug.wsgi import SharedDataMiddleware
app = SharedDataMiddleware(app,
{'/': os.path.join(os.path.dirname(__file__),
'static')})
from socketio.server import SocketIOServer
SocketIOServer(('0.0.0.0', port_num), app,
resource="socket.io", policy_server=False).serve_forever()
I'm able to get the web server started, but when I navigate to the page, this error log gets thrown

I'm not at all sure why this is happening, and if anyone has ever seen something like this before, please share what possible solutions I have to get this to work.
