I'm using tymondesigns/jwt-auth in Laravel and angular application, this is the code i'm using i'm getting token expired error from laravel end in my network tab when idle time is more than 20-30 min but my ttl value is 1440, and front end user should get message in popup that their session expire rather than getting 500 error in console.
