snakeroot What is this error?
Can anyone help me out with this error? System.NullPointerException: Attempt to de-reference a null object
I think what happened was I deployed an app to my sandbox. The app requires some custom settings. So I put in a value for getKey. When I went to deploy, I deleted the custom setting since it wasn't setup before I deployed to my sandbox. Now I'm getting the above error. I'm not sure where to even begin to troubleshoot this. Anyone have any ideas?
I figured this out. It was a line of test code I was using that couldn't reference the custom settings, so the value was null and throwing this error.

Does the error refer to a particular line of code?
Somewhere in your code, you're not checking the return value of a function or method, and you're assuming it was successful and gave you an actual object. If you try to do something to that object, you'll get a NullPointerException.
