Socket IO not supported

[dedtadeas]

Hi,

I have python Socket IO server based on

from flask import Flask, jsonify, request
from flask_socketio import SocketIO
from flask_cors import CORS
import logging

# Flask and SocketIO setup
app = Flask(__name__)
socketio = SocketIO(app, cors_allowed_origins="*", engineio_logger=True)  # Initialize SocketIO once

# Flask CORS
CORS(app, resources={r"/*": {"origins": "*"}})

@socketio.on("connect")
def handle_connect():
    logging.info("Client connected")
...
@socketio.on("disconnect")
def handle_disconnect():
    logging.info("Client disconnected")

if __name__ == "__main__":
    logging.basicConfig(level=logging.DEBUG)
    socketio.run(
        app, host="0.0.0.0", port=20003, debug=False, allow_unsafe_werkzeug=True,
    )

It seems that Socket IO is not supported by this plugin at the moment. When I try to create a connection in Grafana (locally), I receive :
Query A - Starting WebSocket: connection Error: websocket: bad handshake"
On server side I get 404 bad request...

1. I think there should be support for Socket IO for this plugin since it is pretty common.
2. Can u give point me to the WebSocket server implementation, which is compatible with grafana-websocket-plugin?

Thank you!
Best from
