No web processes running Error - Deploying Django on Heroku

Question

I am using the tutorial to deploy Django. [http://devcenter.heroku.com/articles/django] After I do a git push heroku master, there are no web processes.

Process  State  Command  
-------  -----  ------- 

On the log it looks like the following.

2012-04-13T03:48:45+00:00 heroku[slugc]: Slug compilation started

Any ideas? I was able to get this to work with another app. Thank you.

Also when I do a heroku scale web=1 I get this

Scaling web processes...  !    Record not found.

Answer 1

This is most likely the result of scaling your web processes down to zero through the client.

$ heroku ps:scale web=0

Use the heroku ps command to determine the state of your web processes., and you should take a look at the Error Codes to understand the Heroku functionality.

Answer 2

I had the exact same problem. At first, when I ran heroku scale web=1, I got the same 'Record not found' error as you. But I waited a few minutes and ran it again, and it worked.

If your build fails on the first push for some reason, then heroku doesn't automatically give you a web process, and the 'Record not found' error might've cropped up because something was off with the build at that point.
