Dynos field is blank after pushing Django app to Heroku

Question

Programming newb, Trying to use Heroku for the first time for a Django app. After I push it to Heroku, the Dynos field is blank. I expected to see my procfile: web: python manage.py runserver 0.0.0.0:$PORT --noreload

Of course, when I try to open the application on Heroku, I get: An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details

Could this be because I don't have an extension on my procfile?

My Procfile should just be a file I created in my text editor, right?

Here is the log:

Answer 1

Could it be that you forgot to heroku ps:scale web=1 ?

If not, could your Procfile be missing? Your Procfile should be name Procfile (no extension, capital P), and be placed in your project's root. You can check that by heroku run bash and then change in your app's directory and cat Profile.

Finally, if that's already the case then could your app have failed to start and gave up? Are there any other errors in the log?

Answer 2

with the code=H14 in your log you can check the error at: https://devcenter.heroku.com/articles/error-codes#h14-no-web-dynos-running

H14 - No web dynos running
This is most likely the result of scaling your web dynos down to 0 dynos. To fix it, scale your web dynos to 1 or more dynos

You probably did not type heroku ps:scale web=1 after git push heroku master
