How to get logs for Application Error on Heroku

I have been trying to redeploy my app hosted on Heroku.

On every redeploy i was getting "Your app was successfully deployed."

But on opening the page i was getting:

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.

On opening the logs under the 'Activity' tag gave me logs but it had nothing about what went wrong.

How would one get to know whats causing application error.

Solution

  • We could get the logs for Heroku easily from heroku shell. To get 'heroku shell' on you computer, install heroku toolbelt.

    One installed, from 'cmd' login to heroku:

    heroku login

    Then you could get the logs:

    heroku logs --app APPNAME

    This works irrespective of whether you use git, github or dropbox.
