Laravel 5.7: File upload form not working properly

Im having issues with a file upload in laravel 5.7
I think i have done everything correctly but the file never reaches the controller.

Here is my form:

<form action="" method="post" enctype="multipart/form-data">
    @csrf
    <div class="form-group">
        <input id="module" type="file" class="form-control-file" name="module">
    </div>
    <button type="submit" class="btn btn-raised btn-success btn-iconText float-right">Install<i class="material-icons">add_circle_outline</i></button>
</form>

My route:

Route::post('/modules', 'ModuleController@store')->name('modules.store');

My controller function:

public function store(Request $request)
{
    //dd($request->hasFile('module'));
    dd($request->all());

    return redirect()->route('modules.index');
}

The hasFile()-Method returns false. $request->all() contains the following:

array:2 [
  "_token" => "ceMpab3FqZU4qsHo7QTvRwKMTr2zLgc0krbcieJj"
  "module" => "example.png"
]

I have no idea what im doing wrong. Hopefully some can help me.
