Description
I ran into this today when I removed a variable that was in the :bindings configuration. All I got was a null pointer exception, and no stacktrace. It'd be great if there was a more explicit message saying we were trying to bind a variable that didn't exist.

Research direction
Start by locating the code that processes the :bindings configuration and reproduce the failure after removing a referenced variable. Trace where the null pointer exception is produced; done means the missing variable is reported with an explicit error message instead.
