I am trying to automate my daily task on Facebook while at very first I wanted to post a simple message on Facebook however I got this issue even I updated all the necessary permission to grant.

import os
import requests
def post_to_facebook_page(access_token, page_id, message, files=None):
    api_endpoint = f'https://graph.facebook.com/{page_id}/feed'

    # Data to be sent with the request
    data = {
        'message': message,
        'access_token': access_token
    }

    # Send POST request with files if available
    response = requests.post(api_endpoint, data=data, files=files)

    # Check if the request was successful
    if response.status_code == 200:
        print('Post successful!')
    else:
        print('Error posting:', response.json())

if __name__ == "__main__":
    # Facebook credentials
    access_token = 'i_had_also_my_correct_API'
    page_id = 'This_is_also_in_right_id'

    # Message to post
    message = 'Hello, world! This is a test post from Python.'

    # Call the function to post to Facebook
    try:
        post_to_facebook_page(access_token, page_id, message)
    except Exception as e:
        print('An error occurred:', e)

I am expecting an error need to solved with suggestion and correction, however I also asked gpt but didn’t work out at all.
