Client event not received from nodejs socketio server

[pluzmedia]

I can successfully emit to NodeJS socketio from python client by the following code
sio.emit("coords", {"id": rowId})

but emits from the NodeJS sever are not received by python client

NodeJS server code
socket.emit("catch_all", res.id)

Python Client code

@sio.on('catch_all')
def catch_all(data):
    print('message received with ', data)
    sio.emit('coords', {'response': 'my response'})

or

@sio.event
def catch_all(data):
   print('message received with ', data)
   sio.emit('coords', {'response': 'my response'})

Any help?

First of all, what is the logic in writing a bug report against this package when you really just have a question and need help? Bug reports are that, bug reports. If you don't have a bug to report, then don't write one. There is a discussion board that is specifically there for questions like yours.

Now, with regards to your question, I need to see your logs. The troubleshooting section of the documentation explains how to enable logs. Please do that, then add the logs to your question.

NodeJS server recives events find and emit back to the socket but the python client didn't receive the events. Is there anyway to address this?. NodeJS client works fine.

socket.on("coords", async function (res, callback) {
        //let data = JSON.parse(res)
        socket.emit("catch_all", res.id)
        callback(res.id)
        console.log(res);
    });

if the client doesn't log, then the server isn't sending. Even if the server is sending garbage or invalid stuff, the client should log it, and it isn't logging anything. So your next step is to debug your server, and make sure it is sending. If you have a complete example that demonstrates that this is a bug in the client, then provide the code and I'll look at it.

NodeJS socket.io version is [email protected]
Python-socketio client version is 5.4.1

Are those compatible?

Also, what are these lines in your log?

<class 'socketio.exceptions.BadNamespaceError'>

Is your application printing these lines?

yes and as you said the problem lies in the server. I have created separate namespace for this application and it is working great. Thanks for your kindness.
