Websocket Insomnia Flask

Question

I have a short question:

I have this simple flask Server running:

from flask import Flask, render_template
from flask_socketio import SocketIO, emit

app = Flask(__name__)
socketio = SocketIO(app)

@app.route('/')
def index():
    return render_template('index.html')

@socketio.on('message')
def handle_message(message):
    emit('message', message)

if __name__ == '__main__':
    app.run(debug=True, host='127.0.0.1', port=5000)
    socketio.run(app, logger=True, engineio_logger=True)

and I am sending this request in INSOMNIA

But I am always getting a 400. Can you tell me what I am doing wrong?

Many thanks

Are you trying to do a WebSocket or Socket.io? – Diego Borba Sep 01 '23 at 14:04 — Diego Borba, Sep 01 '23 at 14:04
I try to implement it with Socket.io – DrKnowing Sep 01 '23 at 14:09 — DrKnowing, Sep 01 '23 at 14:09

You are sending a WebSocket request to a Socket.io server. However, Insomnia doesn't support Socket.io, only WebSocket. You can see it here and here.
