title: Error Response: [13] An internal error occurred, when deploying project on Google Cloud SDK
body: <p>I have been trying to deploy my project on Google Cloud SDK since yesterday and have been getting the same error over and over.</p>
  
  <p>My app.yaml file looks like:</p>
  
  <pre><code>runtime: python27
  api_version: 1
  threadsafe: yes
  
  - url: /
    static_files: bin/index.html 
    upload: bin/index.html
  
  - url: /assets
    static_dir: bin/assets 
  
  - url: /src
    static_dir: bin/src
  
  - url: /vendor
    static_dir: bin/vendor
  
  - url: /templates-app.js
    static_files: static/templates-app.js 
    upload: static/templates-app.js
  
  - url: /templates-common.js
    static_files: static/templates-common.js 
    upload: static/templates-common.js
  
  - url: .*
    script: main.app
  </code></pre>
  
  <p>I use this command to deploy:</p>
  
  <blockquote>
    <p>gcloud preview app deploy app.yaml --version 1 --promote --force</p>
  </blockquote>
  
  <p>And I get this error:</p>
  
  <pre><code>Beginning deployment...
