XMPP threaded receiver in Python 3

What I want to do is set up an XMPP receiver using the Slixmpp library which listens for messages throughout the script execution. I think the threading library might provide a solution so tried that. This script is for an online PvP game and I need to receive information from the opponent continuously.

This is the code I have tried:

import time
import threading as td
import slixmpp as slix
import logging
import asyncio

my_jid = "[email protected]"
my_pass = "test"

class receiver(slix.ClientXMPP):
    def __init__(self, jid, password):
        slix.ClientXMPP.__init__(self, jid, password)
        self.add_event_handler("session_start", self.start)
        self.add_event_handler("message", self.message)

    def start(self, event):
        self.send_presence()
        self.get_roster()

    def message(self, msg):
        if msg['type'] in ('chat', 'normal'):
            msg.reply("Thanks for sending\n%(body)s" % msg).send()
            print(msg['body'])

def function():
    recv = receiver(my_jid, my_pass)
    recv.connect()
    recv.process()



newthread = threading.Thread(target=function)
logging.basicConfig(level="DEBUG", format='%(levelname)-8s %(message)s')


newthread.start()

input("Press Enter to continue")

This returns the following error:

Exception in thread Thread-1:

In my case executing:

newthread.daemon = True

Before calling:

newthread.start()

Works as expected creating a non-blocking thread.
