favicon.ico “not found error” in App Engine

Question

I am trying to develop on Google App Engine and in the list of the errors displayed in the admin console I always see the following:

/favicon.ico

Answer 1

For your application, favicon.ico should be a static image. You can upload a favicon.ico file with your application, and in your app.yaml file configure your application to serve the image when the url /favicon.ico is requested. Below is an example entry in your app.yaml file for /favicon.ico. We assume you include the favicon.ico file in the directory path static/images:

- url: /favicon.ico
  static_files: static/images/favicon.ico
  upload: static/images/favicon.ico
