This is expected and you can safely ignore this error. The app continues to run. There is no favicon.ico file included in the tutorial, so it cannot be found.

You can add a favicon along with an add_static_view to resolve the error message.

Yes, I fixed it just as you say. Could a favicon be added to the tutorials to avoid confusion? Thanks.

[stevepiercy]

Well, it could, but then you wouldn't have a puzzle to solve, would you? :wink:

Keep in mind this is a "Quick Tutorial", and is not designed to be complete or comprehensive. Each step focuses on a single given topic. In this step, forms are the focus. Static assets is in Step 13.

That said, this would be a good Extra Credit question in the tutorial documentation where it first occurs.
