Running disqus_export on django-disqus app

I'm trying to export Django comments to the django-disqus app. When I run python manage.py disqus_export --verbosity=0, I get the following error lines:

The --dry-run command works, however, so I'm not sure what's going on.

Disqus may return a 400 if invalid credentials are provided. It's been a while since I've looked at django-disqus, but can you confirm that whatever credentials you've supplied are valid?
