Issue with the "Run a Flask App" doc

I found an issue with this document.

Title: Run a Flask App
Location: https://fly.io/docs/python/frameworks/flask/
Source: https://github.com/superfly/docs/blob/main/python/frameworks/flask.html.markerb

Describe the issue

I was running the Run a Flask App tutorial (https://fly.io/docs/python/frameworks/flask/), everything was running fine until the last step, when deploying fly i received this error '''Error: failed to fetch an image or build from source: app does not have a Dockerfile or buildpacks configured.'''

hey! To clarify, did you run through the "build a flask app from scratch" or through the "speedrun"?

In addition:

• did you try re-running fly launch?
• if so, could you specify which OS you are on?
• and could you provide the output you get from fly launch?

Thanks for reporting! :)

Having just run through this - I did the "build a flask app from scratch" steps and it worked fine, on macOS.
