           if (function == null) 
        
               throw new CarpetExpressionException("UNDEFINED", null);

Maybe something like "couldn't find function (name) [in app (appname)]".

Expanded suggestion with proper placeholders: "Can't find function A in app B"

Oh lol github stripped them as html tags, they were there.

yeah, why not

	if (function == null)
	throw new CarpetExpressionException("UNDEFINED", null);
