`TypeError: can only concatenate str (not "bytes") to str` when connecting with ejabberd server

import socket
from socketfunc import *

server="localhost"
 
jid = JID(user) 
connection = Client(server) 
connection.connect()
result = connection.auth(jid.getNode(),password) 
connection.sendInitPresence()

I have a user joker registered on ejabberd server with the same username and password and i am trying to connect and open a session with the ejabberd server but running the above code leads to the below issue

 Traceback (most recent call last):
  File "test.py", line 79, in <module>
    result = connection.auth(jid.getNode(),password)

    self.DEBUG('Got challenge:'+data,'ok')
TypeError: can only concatenate str (not "bytes") to str

However i am able to connect to prosody xmpp server using the same above code but ofcourse different user credentials.

Please look into this issue

Thanks

I have the same problem! Do you have any clue how to solve this?

Are you using python2.7? This looks a bit like using python3 on python2.x code.

@gdt Double checked. My code from example https://pastebin.com/wijSmn1z. Output from "python3.8 test.py" -> https://pastebin.com/hx8ZsCmz.
And it didn't get the msg. (

Hi there,

thanks for writing in. Can you give the patch from #45 a try?

python3 -m venv .venv
source .venv/bin/activate
pip install git+https://github.com/xmpppy/xmpppy.git@amo/fix-python3

wget https://pastebin.com/raw/wijSmn1z -O test.py
python test.py

With kind regards,
Andreas.

P.S.: This module is primarily maintained for Python 2, while we slightly improved compatibility with Python 3. In any case, I want to also recommend https://github.com/poezio/slixmpp by @poezio and contributors.

Thanks, the problem with error is gone! But I still can't connect and send msg. Maybe this time I am doing something wrong.) (log after executing https://pastebin.com/hGVeEe1v). Thanks for the advice about slixmpp. I will test it and will update the issue if the problem was on my side)

Dear @mnswdhw, @M010 and @gdt,

#45 most probably resolved this error already, so I am closing this. Please let us know if you still observe any problems on this matter.

With kind regards,
Andreas.
