title: App yaml configuration issue when deploying angular 7 website and google app engine API's
body: <p>I am trying to deploy an Angular7 application in Google App Engine with backend endpoints in python2.7.And here I am getting handlers error: </p>
  
  <blockquote>
    <p>Static file referenced by handler not found:
    dist/_ah/api/sampleApi/v1/users</p>
  </blockquote>
  
  <p>Both Angular dist folder and API's when configured in app.yaml fails.</p>
  
  <p>If API's configuration is removed from app.yaml Angular website works.
  If Angular dist is removed from app.yaml API's work from the postman.</p>
  
  <pre><code>handlers:     
  - url: /        
    static_files: dist/index.html         
    upload: dist/index.html      
    secure: always       
  - url: /       
    static_dir: dist      
  - url: /_ah/api/.*    
    script: sample.api   
  </code></pre>
  
  <p>My project Structure is:</p>
  
  <pre><code>project-folder   
     -- app.yaml    
     -- endpoint source code files    
     -- dist folder (for angular)    
  </code></pre>
