Laravel - Form validation error - argument 2 must be array

Question

I'm working with Laravel and every time I submit my form it gives me this error:

ErrorException in Factory.php line 91: Argument 2 passed to Illuminate\Validation\Factory::make() must be of the type array, null given, called in /var/www/vendor/laravel/framework/src/Illuminate/Foundation/Http/FormRequest.php on line 83 and defined

This is some code for the controller, even when I don't try to send data to the database it gives me this error. (now it's just redirecting)

public function store(StoreProjectRequest $request)
{


    return Redirect::to('/index');

}

This is how I defined my routes:

Route::get('/projects','ProjectsController@index');
Route::get('/create','ProjectsController@create');

Route::post('/create','ProjectsController@store');

The line the error refers to is what is in the return section here:

protected function getValidatorInstance()
{
    $factory = $this->container->make('Illuminate\Validation\Factory');

    if (method_exists($this, 'validator')) {
        return $this->container->call([$this, 'validator'], compact('factory'));
    }

    return $factory->make(
        $this->all(), $this->container->call([$this, 'rules']), $this->messages(), $this->attributes()
    );
}

Can anyone help me? Thank you!

You need to post the code for your Validator::make(). Make sure the first parameter is the input array eg: $request->all() and the second parameter is your rules array eg: ['email' => 'required|email'...] — Sandyandi N. dela Cruz

I had a partial installation of the framework which produced exactly this same error. I copied all the files across again (restoring missing files) and then the problem went away. — Eugene van der Merwe

Problem is in your StoreProjectRequest and it's rules() method. It should return array and in your code it probably returns something else. Check it, please.

Got similar error for Maatwebsite\Excel\Imports\ModelManager::add(): Argument #2 ($attributes) must be of type array, null given.

Used WithValidation class method public function prepareForValidation($data, $index), but made the mistake not adding return $data inside this method.
