couldn't find that process type

Question

I am having trouble with the "couldn't find that process type" error on Heroku. I submitted a ticket Thursday but still don't have a solution and they are not open for folks like me on the weekend, so I am posting here.

Please note:

1. This is a Django app
2. It runs locally on both heroku local and django runserver, but not heroku itself.
3. I was following a solution I read here: Couldn't find that process type, Heroku which was to take the Procfile out, do a commit, then put it back, and do a commit, and it should work.

The output from the push to Heroku was the same:

remote:        Procfile declares types -> (none)

So Heroku didn't even notice that the Procfile was missing?!

Then I put the Procfile back and I still get the same error:

2019-06-08T18:49:34.853568+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/" host=lj-stage.herokuapp.com request_id=d592d4e6-7558-4003-ab55-b3081502f5cf fwd="50.203.248.222" dyno= connect= service= status=503 bytes= protocol=http

I've also read about multiple buildpacks needing to be in a certain order, which might cause this error, but I only have one:

(hattie-nHCNXwaX) malikarumi@Tetuoan2:~/Projects/hattie/hattie$ heroku buildpacks
 ›   Warning: heroku update available from 7.7.8 to 7.24.4
=== lj-stage Buildpack URL
heroku/python

Furthermore, I did a word search through the Python buildpack on GitHub and didn't see anything to indicate the buildpack is doing anything other than rely on the Procfile for process types.

I also tried heroku ps:scale web=1, which gives the 'couldn't find that process type' error.

There are several other similar questions here on SO, a lot of them don't have answers, and I tried the ones that did. Any assistance greatly appreciated.

update: As requested, here is my tree. The names next to Procfile are Django models:

And here is the content of my Procfile:

web: gunicorn hattie.wsgi --log-file -

Answer 1

Your Procfile must be in the root of your repository. Move it there and redeploy.
