CUSTOM script error: require is not defined

Server-Side Scripting
1

Hello All,

i have Dreamfactory(V2.1) on centOS 6
“require is not defined” is returned when i try to run custom script with require()

var lodash = require("lodash.min.js");

var params = event.request.parameters;
var required = ["voucher_code","card_id"];
lodash._.each( required, function( element ) {
    if (!params.hasOwnProperty(element) || !params[element]) {
        throw new Error( "Missing '" + element + "' in params\n" );
    }
});

this is my V8js configuration
