If it has worked for you before then you should check if you have messages defined in the applangenvalidation.php or by chance you have changed the locale of the app and have not defined the messages for it. There are many possibilities.

laravel validation

Rule::unique('users')->ignore($user)

laravel validation

"foo" => "Your input was invalid!",

"accepted" => "The :attribute must be accepted.",

// The rest of the validation error messages...

laravel validation

$rules = ['name' => 'unique:users,name'];

$input = ['name' => ''];

Validator::make($input, $rules)->passes(); // true
