How to slove this error in laravel "Name and email address are required if not a client"

I'm getting an error as "Name and email address are required if not a client" while running the below mentioned code.

Find below the Controller Code:

class UserController extends Controller
{

public function insertform(){
    return view('test');
    }

    public function create(){
        $user=Whmcs::AddClient([
            'firstname' => Input::get('firstname'),
            'lastname' => Input::get('lastname'),
            'email' => Input::get('email'),
            'address1' => Input::get('address1'),
            'city' => Input::get('city'),
            'state' => Input::get('state'),
            'postcode' => Input::get('postcode'),
            'country' => Input::get('country'),
            'phonenumber' => Input::get('phonenumber'),
            'password2' => Input::get('password2'),

        ]);
        return $user;
    }
 }

Find below the route code:

Route::get('insert', 'UserController@insertform');
Route::post('create', 'UserController@create')->name('user.create');

The blade file is given below
