Spotify Error 401 even though I, supposedly, have access_token (Python)

Question

import requests
import base64
    
# Request an access token
def request_access_token():
    AUTH_URL = 'https://accounts.spotify.com/api/token'

    # POST
    auth_response = requests.post(AUTH_URL, {
        'grant_type': 'client_credentials',
        'client_id': "<client ID>",
        'client_secret': "<client Secret>",
    })

    # convert the response to JSON
    auth_response_data = auth_response.json()

    # save the access token
    print(auth_response_data)
    access_token = auth_response_data['access_token']

    return access_token

# Check if the access token is valid
def check_access_token_validity(access_token):
    headers = {
        "Authorization": f"Bearer {access_token}"
    }
    response = requests.get("https://api.spotify.com/v1/me", headers=headers)
    print(response)
    if response.status_code == 200:
        return True
    else:
        return False

# Run the code
access_token = request_access_token()

if access_token:
    if check_access_token_validity(access_token):
        print("Access token is valid.")
    else:
        print("Access token is not valid.")
else:
    print("Could not request access token.")

I get a "access_token" but it doesn't work. It gives Error 401. I also got the same issue in javascript. I tried everything and I dont know what is wrong. Here's the output:

output

Which shows that I did recieve a token. But when I try to check it's validity, it is [Invalid 401]. I have also rotated my client secret and same issue. Both Client ID and Client Secret are correct.

As mentioned in the docs, your access token request is different

Try this

import requests
import base64

client_id = 'CLIENT_ID';
client_secret = 'CLIENT_SECRET';

response = requests.post(
    'https://accounts.spotify.com/api/token',
    data={'grant_type':'client_credentials'},
    headers={'Authorization': 'Basic ' + base64.urlsafe_b64encode((CLIENT_ID + ':' + CLIENT_SECRET).encode())},
)
