@jwt.unauthorized_loader error handler doesn't work

Hi.
This Poorya.
I wrote an error handler for my Flask application. This application uses Flask JwT Extended and Flask Socket-io libraries for authentication real-time communication. My error handler doesn't work and gives an error.(@vimalloc, could you please take a look at this issue?)
My code:

from flask import Flask, jsonify, request
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
from flask_jwt_extended import JWTManager, jwt_required, create_access_token, get_jwt_identity
from flask import Flask
from flask_socketio import SocketIO, emit, disconnect
from flask_jwt_extended.exceptions import (
    NoAuthorizationError,
    InvalidHeaderError,
)


# Initialize Flask app
app = Flask(__name__)

port = xxxx
host = "xxx.xxx.xxx.xxxx"

# Configurations
app.config['SECRET_KEY'] = "sdkjfh234"
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///users.db'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
app.config['JWT_SECRET_KEY'] = 'sdkjfh234'  # Change this to a random secret
app.config['PROPAGATE_EXCEPTIONS'] = True

# Initialize extensions
db = SQLAlchemy(app)
migrate = Migrate(app, db)
jwt = JWTManager(app)
socketio = SocketIO(app)


# User model
class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(80), unique=True, nullable=False)
    password = db.Column(db.String(128), nullable=False)

# Route for user registration
@app.route('/signup', methods=['POST'])
def signup():
    data = request.get_json()
    username = data.get('username')
    password = data.get('password')

    # Check if username already exists
    if User.query.filter_by(username=username).first():
        return jsonify({"msg": "Username already exists"}), 400

    # Create a new user
    new_user = User(username=username, password=password)  # Hash the password in a real app
    db.session.add(new_user)
    db.session.commit()
    return jsonify({"msg": "User created successfully"}), 201

# Route for user login
@app.route('/login', methods=['POST'])
def login():
    data = request.get_json()
    username = data.get('username')
    password = data.get('password')

    user = User.query.filter_by(username=username).first()

    # Check if user exists and password is correct
    if user and user.password == password:  # Hash comparison needed in a real app
        access_token = create_access_token(identity={'username': user.username})
        return jsonify(access_token=access_token), 200
    return jsonify({"msg": "Bad username or password"}), 401

# Protected route
@app.route('/protected', methods=['GET'])
@jwt_required
def protected():
    current_user = get_jwt_identity()
    return jsonify(logged_in_as=current_user), 200


# @jwt.unauthorized_loader
# def handle_no_authorization_error(error):
#     print(error)
#     print("***************************************ERROR********************************")

#     return jsonify({"error": "Permission Denied"}), 403

# @jwt.invalid_token_loader
# def handle_no_authorization_error(error):
#     print(error)
#     print("***************************************ERROR********************************")

#     return jsonify({"error": "Permission Denied"}), 403

# @app.errorhandler(InvalidHeaderError)
# def handle_no_authorization_error(error):
#     print(error)
#     print("***************************************ERROR********************************")
#     return jsonify({"error": "Permission Denied"}), 403

# Handle missing or invalid JWTs
@jwt.unauthorized_loader
def handle_no_authorization_error(error):
    return jsonify({"error": "Permission Denied"}), 403

@jwt.invalid_token_loader
def handle_invalid_token_error(error):
    return jsonify({"error": "Invalid Token"}), 403

# SocketIO event for authenticated connections
@socketio.on('connect')
@jwt_required()
def handle_connect():
    try:    
        print("connected!!!")
        identity = get_jwt_identity()
        print(f"User {identity} connected")
        emit('message', {'message': 'User connected'})

    except Exception as e:
        print(e)
        disconnect()
        return False
    
    except jwt.invalid_token_loader as e:
        print("Error:", e)
        disconnect(namespace="message")
        return jsonify({"Error": "Invalid Token!!!"}), 403
    
    except jwt.token_verification_failed_loader as e:
        print("Error:", e)
        disconnect(namespace="message")
        return jsonify({"Error": "Token Verification Failed!!!"}), 403
    


    
# Websocket on message 
@socketio.on("message")
# @jwt_required()
def handle_message(message):

    print("Recieved message:", message)
    emit('message', message)

    
    

# Main entry point
if __name__ == '__main__':
    # db.create_all()  # Create database tables
    # with app.app_context():
    #     app.run(debug=True, host=host, port=port)
    socketio.run(app, host=host, port=port, debug=True)

And the error I got:

flask_jwt_extended.exceptions.NoAuthorizationError: Missing Authorization Header

The issue names the @jwt.unauthorized_loader and @jwt_required() entry points and shows the failure in flask_jwt_extended/view_decorators.py during Flask-SocketIO connection handling. Start by reproducing a connection without an Authorization header and trace how the decorator interacts with the SocketIO handler; done requires a confirmed handler behavior or a documented limitation.
