I am using OAuth authentication to fetch the Access token using python. Below is my code snippet
from oauthlib.oauth2 import BackendApplicationClient
from requests_oauthlib import OAuth2Session
client = BackendApplicationClient(client_id=OAUTH_CLIENT_ID)
oauth = OAuth2Session(client=client)
token_details = oauth.fetch_token(token_url=OAUTH_TOKEN_URL, client_id=OAUTH_CLIENT_ID, client_secret=OAUTH_CLIENT_SECRET)
When I try to fetch the token I am facing the below error.
