java.lang.NullPointerException when using Facebook Module on Android

Using the latest Facebook (v2.12) module with Trigger.io (platform v2.2.14), attempting to "Login with Facebook" causes the app to crash and shows the following in the log:

I have double-checked App ID, Key Hash, and relevant settings on Facebook, but the error keeps occurring. Has anyone experienced the same issue and how did you fix it?
