Estou tentando configurar o Google App Engine e o Wordpress versão 3.8 de acordo com as instruções emhttps://developers.google.com/appengine/articles/wordpress

Mas quando eu corro$ APP_ENGINE_SDK_PATH/dev_appserver.py APPLICATION_DIRECTORY Eu tenho o erro

Não foi possível atribuir valor 'wordpress /.. (htm | html | css | js) $ 'para atribuir' upload: 'value' wordpress /.. (htm | html | css | js) $ 'para upload não corresponde à expressão' ^ (?: (?! \ ^). * (?! \ $).) $ 'no app.yaml na linha 9, coluna 11

Aqui está o conteúdo do meu arquivo app.yaml:

application: thangvmwordpressdemo
version: 1
runtime: php
api_version: 1

handlers:
- url: /(.*\.(htm|html|css|js))$
  static_files: wordpress/\1
  upload: wordpress/.*\.(htm|html|css|js)$
  application_readable: true

- url: /wp-content/(.*\.(ico|jpg|png|gif))$
