$matches is empty in some situations. What would you expect to return if your regex fails?

@babai9 If you are using xamp, why are you using php artisan serve? Doesn't xamp provide you with your environment?

@jaseofspades88 For running the laravel project I am using artisan command as it is laravel way, I have previously used in other versions there was no issue

@babai9 I'd try refreshing your application. From root
rm -rf vendor
composer install
The command you're having problems with is baked into Laravel

@jaseofspades88 This is freshly installed version so why do I require this?
