Configuration issue with Github OAuth

Hi all,

I have tried to cover my bases by searching for any related issues, but so far, nothing has helped to resolve this one.

The setup is:

- ubuntu 16.04 vagrant VM

* public network, bridged

- python 3.6

- jupyterhub 0.7.2

- Github OAuth

Using the url: https://some_ip, I get the redirect to the Github sign-in and like others, once signed in, I get a 404 message with this url:

https://github.com/login/oauth/authorize?redirect_uri=https%3A%2F%2F129.236.40.168%2Fhub%2Foauth_callback&client_id=&response_type=code

I noticed that the client_id is empty. I read the jupyterhub/oauthenticator issue #69 which was an issue with mismatching client id's, but I've checked that the client id as it appears on Github is the same as in the configuration file.

If I copy+paste the client id from the configuration file into the url I get a 500 (internal server error) message.

Here is the jupyterhub_config.py:

c.JupyterHub.ssl_key = '/etc/jupyterhub/jupyterhub.key'

c.JupyterHub.ssl_cert = '/etc/jupyterhub/jupyterhub.crt'

c.JupyterHub.port = 443

c.JupyterHub.hub_ip = 'some_ip'

c.JupyterHub.hub_ip_connect = 'some_ip'

c.JupyterHub.authenticator_class = 'oauthenticator.GitHubOAuthenticator'

c.LocalAuthenticator.create_system_users = True

c.GitHubOAuthenaticator.client_id = os.environ['GITHUB_CLIENT_ID']

c.GitHubOAuthenaticator.client_secret = os.environ['GITHUB_CLIENT_SECRET']

c.GitHubOAuthenticator.oauth_callback_url = 'https://some_ip/hub/oauth_callback'

I acknowledge that this is very likely a configuration blunder on my part, but I am quickly exhausting the low-hanging fruit.

Any help would be appreciated.

Chris

I'm not sure if this is the issue, but there is a typo in your configuration: `c.GitHubOAuthenaticator` should be `c.GitHubOAuthenticator`.

Boy do I feel sheepish. That was indeed the issue. I don't know how that escaped me. Thanks so much for the proof reading.
