TemplateNotFound: index.html с Google App Engine и Jinja2

Я пытаюсь собрать свой первый Приложение GAE с jinja 2. После преодоления дюжины мелких ошибок, теперь я застрял с этим:

Traceback (последний последний вызов):

File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2\webapp2.py", line 1536, in __call__
    rv = self.handle_exception(request, response, e)
  File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2\webapp2.py", line 1530, in __call__

    raise TemplateNotFound(template)
TemplateNotFound: index.html

Вот мой файл yaml:

application: himother
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.app

libraries:
- name: webapp2
  version: "2.5.1"
- name: jinja2
  version: "2.6"

Вот мой код:

import os
import webapp2

import jinja2

jinja_environment = jinja2.Environment(autoescape=True,
    loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__), 'templates')))

class MainPage(webapp2.RequestHandler):
    def get(self):
        template_values = {
            'name': 'Serendipo',
            'verb': 'extremely happy'
        }

        template = jinja_environment.get_template('index.html')
        self.response.out.write(template.render(template_values))

app = webapp2.WSGIApplication([('/', MainPage)],
                              debug=True)

Вот мой шаблон .html:

<!DOCTYPE html>
<html>
    <head>
        <title>Look Ma, I'm using Jinja!</title>
    </head>
    <body>
        Hi there - I'm {{ name }}, and I {{ verb }} programming!
    </body>
</html>

Несмотря на сообщение об ошибке, у меня есть папка с именем «шаблоны», и в ней создан файл index.html:
