Error in RoutesParser.cfc

[robmarzialetti]

I get this error:
Cannot return first element of array; array is empty

in: RoutesParser.cfc
line: 432

I had to make this change to the code to get it to work, set to empty fullEvent variable and comment the followed line:

    fullEvent = "";
    if ( !len( handlerRoute ) && isStruct( arguments.route.action ) ) {
        //var fullEvent = arguments.route.action[ arguments.route.action.keyArray().first() ];
    }

This is mine "arguments.route"

Maybe I'm doing something wrong in the setup?

Many thanks!
