Saya lagi buat project belajar express dengan handlebars menggunakan template adminlte. Folder AdminLTE sudah saya letakkan dalam direktori "public" lalu saya buat folder baru "layouts" yang terdiri dari 6 file hbs (base (base.hbs adalah default layout), footer, head, js, nav, sidebar) didalam folder "/views/" dan saat dijalankan "nodemon start" berjalan lancar tanpa error, tapi hanya saat coba akses localhost:3000 langsung muncul error: "TypeError: Cannot read property 'hash' of undefined"

Ini potongan code utk handlebars di file app.js

var hbs = require('express-handlebars');

var routes = require('./routes/index'); var users = require('./routes/users');

var app = express();

// view engine setup // app.engine('hbs', hbs({extname: 'hbs', defaultLayout: 'base', layoutDir: __dirname + '/views/layouts'})); app.engine('hbs', hbs({ extname: 'hbs', defaultLayout: 'base', partialsDir: __dirname + '/views/layouts', registerPartials: __dirname + '/views/layouts', layoutDir: __dirname + '/views/layouts' })); app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'hbs');

// uncomment after placing your favicon in /public //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public')));

berikut ini isi file base.hbs:

{{> head}}

{{> nav}} {{> sidebar}}

{{{ body }}}

{{> footer}}

{{> js}}

Kira-kira dimana ya letak salahnya ?

Terima kasih.
