Why am I getting a 404 error on a repository that exists?

Typically, we send a 404 error when your client isn't properly authenticated. You might expect to see a 403 Forbidden in these cases. However, since we don't want to provide any information about private repositories, the API returns a 404 error instead.

To troubleshoot, ensure you're authenticating correctly, your OAuth access token has the required scopes, and third-party application restrictions are not blocking access.
