Wordpress Error uploading image: 401 API Python Script

I have this script in python to try to upload an image. But First I added one ‘Application Password’ in my profile of wordpress. I have the key and all the user name is ‘admin’

However, the script gives me this error:

‘Error uploading image: 401 - {"code":"rest_cannot_create","message":"Sorry, you are not allowed to create posts as this user.","data":{"status":401}}
Image upload failed.’

What could be wrong or I miss to configure?

This is the script:

import requests
from requests.auth import HTTPBasicAuth
import os
import base64

# WordPress API credentials
WP_USER = 'admin'  # Your WordPress username
WP_APPLICATION_PASSWORD = 'xxx'  # Your WordPress application password
WP_URL = "https://xxx.xxx.com"  # Your WordPress site URL

def upload_image_to_wp(imgPath):
    """
    Upload an image to WordPress via the REST API using application password authentication.
    
    :param imgPath: Local path to the image to upload.
    :return: The image ID and URL if successful, else None.
    """
    url = f'{WP_URL}/wp-json/wp/v2/media'

    # Create the Authorization header manually
    auth = HTTPBasicAuth(WP_USER, WP_APPLICATION_PASSWORD)
    auth_header = {
        'Authorization': 'Basic ' + WP_USER + ':' + WP_APPLICATION_PASSWORD,
        'Content-Type': 'image/jpeg' if imgPath.endswith('.jpg') or imgPath.endswith('.jpeg') else 'image/png',

    }

    with open(imgPath, 'rb') as file:
        file_data = {

        }

        # Adding Content-Disposition header
        headers = {
            'Content-Disposition': 'attachment; filename="image.jpg"'  # Adjust filename as needed
        }

        try:
            response = requests.post(url, files=file_data, headers={**auth_header, **headers})

            if response.status_code == 201:
                new_dict = response.json()

            else:
                print(f"Error uploading image: {response.status_code} - {response.text}")
                return None
        except requests.exceptions.RequestException as e:
            print(f"Request error: {e}")
            return None

# Example usage
image_path = r"C:/jpg.jpg"  # Replace with the actual path to the image
upload_response = upload_image_to_wp(image_path)

if upload_response:
