Laravel Error "$errors is undefined"

Case: In a Laravel project, when you try to get the form validation error object but it fail. 

    $errors is undefined

Reason: Laravel passes the errors variable from the controller to the view file via session. The $errors variable is bound to the view by the Illuminate\View\Middleware\ShareErrorsFromSession middleware, which is provided by the web middleware group. So when you do not declare the web middleware group (containing middleware \Illuminate\View\Middleware\ShareErrorsFromSession) for your route, you will get the error as seen.

Solution: Check your route to make sure you added ShareErrorsFromSession Middleware

Solved !
