How to troubleshoot/debug lightning app page.

When I include my custom component (.cmp) inside of a lightning app page (.app), I get a generic error:

This page has an error. You might just need to refresh it. Aura.loadComponent(): Failed to initialize application. An internal server error has occurred Error ID: 1165864723-88707 (1861465479)

To find out more details about what is causing the issue, I have:

  1. Enabled debug mode so that I get un-minified js code.

  2. Disabled caching

  3. Installed Lightning Inspector for Chrome

When I load the page, I do not see errors in the Google Dev Tools console or Lightning console. I'm lost as far as how to find out details about the error...
