Cannot read property 'set' of undefined

I recently updated my laravel project from 5.2 to 5.3, I also updated Laravel Spark to 2.0 after that, I receive this error :

"Cannot read property 'set' of undefined"

It says it's a javascript error,

if (Cookies.get('XSRF-TOKEN') !== undefined) { request.headers.set('X-XSRF-TOKEN', Cookies.get('XSRF-TOKEN')); }
