I’m new to Python, and I am trying to get through the oauth token fetch. I am getting this error:

**CustomOAuth2Error** : ({'status': 400, 'reason': 'Bad Request', 'message': 'Illegal client_id', 'code': 'OAUTH_ERROR'}

Here’s my code, just taken from the help doc (redacted my username and secret) -

from oauthlib.oauth2 import BackendApplicationClient

from requests_oauthlib import OAuth2Session



# Your client credentials

client_id = 'fake user'

client_secret = 'fake password'



# Create a session

client = BackendApplicationClient(client_id=client_id)

oauth = OAuth2Session(client=client)



# Get token for the session



token = oauth.fetch_token(token_url='https://services.sentinel-hub.com/oauth/token',

   client_secret=client_secret)



# All requests using this session will have an access token automatically added



resp = oauth.get("https://services.sentinel-hub.com/oauth/tokeninfo")

print(resp.content)
