I am having the exact same issue. I tried building the default python test app you have in your docs, and the only diversion I took from the instructions was to provision a Postgres instance during the flyctl launch step.
I’ve tried deploying twice with the same result:

Hey, it looks like there might be an issue with the procfile, from this ModuleNotFoundError: No module named ‘server’. Check that the procfile has this line web: gunicorn hellofly:app, it should be hellofly:app instead of server:app (which I’m guessing is the issue).
Another possibility to troubleshoot would be to change the builder in your fly.toml to heroku/buildpacks:18. In general, buildpacks can be a bit finicky and a more reliable solution would be to create a specific dockerfile for the project and build locally instead of relying on the remote builder.
I tried the solution suggested above by edting this in the Procfile server → hellofly since I also received the same error in the original post. I noticed after the error that it created an extra application:
# fly ls apps
NAME | STATUS | ORG | DEPLOYED
-----------------------------*----------*----------*----------------
...
fly-builder-rough-sky-4968 | deployed | personal |
misty-field-8977 | dead | personal | 9 minutes ago
the ‘fly-builder-rough-sky-4968’ is the extra unexpected app while ‘mist-field-8977’ is what I was expecting and what is in my fly.toml:
app = "misty-field-8977"
Procfile:
# Modify this Procfile to fit your needs
web: gunicorn server:app
I changed the Procfile to:
# Modify this Procfile to fit your needs
web: gunicorn hellofly:app
Then I deleted the extra app
# fly destroy fly-builder-rough-sky-4968
and tried to deploy again:
# fly deploy
It worked, but again created an extra app:
# fly ls apps
NAME | STATUS | ORG | DEPLOYED
---------------------------------*----------*----------*----------------
...
fly-builder-quiet-firefly-2392 | deployed | personal |
misty-field-8977 | running | personal | 7 minutes ago
I ran this example app yesterday with no issues nor an extra app being created.

Ah, yes. So that app misty-field-8977 is the remote builder that we use to build your docker image. It runs when you make a new deploy and dies after a time on inactivity. If you don’t want that app to exist, you’d need to create a docker file and build a docker image locally and run fly deploy --local-only
Don’t you mean that the fly-builder-quiet-firefly-2392 is the remote builder? I ran into the issue when fly deploy prompted me, asking if I wanted to overwrite the Procfile. I figured it knew what it was doing so I said yes and it replaced ‘hellofly’ with ‘server’ which I believe should be the name of the file (minus the ‘.py’ extension) of the flask app. I made pull request to the documentation adding this note in case y’all are interested. Thanks!

Ah yes, my bad. Thanks for the PR!
