Expected result
No server error

I think setting initial_parent_id to '' in the except block on L559 should solve the issue.

 538 def new_document(request):
 539     """Create a new wiki document."""
 540     initial_parent_id = request.GET.get('parent', '')
 554     if initial_parent_id:
 555         try:
 556             parent_doc = Document.objects.get(pk=initial_parent_id)
 557             parent_slug = parent_doc.slug
 558             parent_path = request.build_absolute_uri(parent_doc.get_absolut     e_url())
 559         except Document.DoesNotExist:
 560             logging.debug('Cannot find parent')

Summary: Kuma docs/new 500 error → [traceback] DoesNotExist: User matching query does not exist. Kuma docs/new 500 error
Not sure if we want to fix this. Many/most users are missing from developer-dev because it's a dev sandbox.

We might want to return a default/system user when users aren't found though.

Marking this as WONTFIX as per comment 2. Luke, do we still want to return a default/system user? I can open a separate bug for that.

Forgot to mark this as WONTFIX. Doing that now, but the question still stands.

Let's wait on that. The main annoyance is the server error email, which will go away with Sentry.
