Heroku app successfully deploying, but receiving application error when loading site

 原文  2019-04-22 20:54:03  4   4    python/ django/ heroku

Question

My logs don't indicate any errors as far as I can tell, but I'm receiving the following error when loading the site:

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail

Below you can find the logs. Am I missing something here?
