This application does not exist (app_id=xxx)

Question

I was unable to upload to an AppEngine as appcfg was telling me :

This application does not exist (app_id=u\'xxx\').

Answer 1

You have to log in in your gae account and create an application before you upload it, and your app_id has to have the same name as you app. You can't just upload it.

So go here, create your app, for example "example_app" and set the app_id=example_app and everything should work :)
