Response.php第403行中的UnexpectedValueException - Laravel 5.3

Question

I am new to Laravel and am building a small project as my schooling. I have struck the above error and I cannot seem to fix it. Any help is appreciated.

I am using sentinel package for authentication.

Web.php

Route::post('/login' , 'LoginController@login');

LoginController.php

public function login(Request $request){
       Sentinel::authenticate($request->all());
       return Sentinel::check();

}

When I click on submit button then this error showing:

UnexpectedValueException in Response.php line 403: The Response content must be a string or object implementing __toString(), "boolean" given.

Finally i solved the problem .

Actually i forget to replace email to username in EloquentUser.php because i am using username unique rather than email .

 protected $loginNames = ['email']; ->  protected $loginNames = ['username'];
