tornado.web.HTTPError: HTTP 404: Not Found

Issue:

When accessing the /auth/github route, the Tornado server raises a tornado.web.HTTPError: HTTP 404: Not Found. This indicates that the requested URL endpoint is not registered or recognized by the application, resulting in a missing handler for GitHub authentication.

To resolve this issue, I propose adding or verifying the registration of the /auth/github route within the Tornado application's URL mappings. Specifically:

Ensure the URL pattern is included:

1.Add an entry for /auth/github in the Tornado Application routes list
2.Implement the corresponding handler:
Verify that GitHubAuthHandler exists and correctly handles the OAuth flow with GitHub.
3.Validate configuration:
Confirm any related OAuth client credentials and environment variables are properly set up for the authentication process to work.
