custom image upload option in jodit editor by laravel

I'm coding the editor in the Laravel framework and implementing the Jodit library. I want to add an upload for the editor. The problem is that the upload does not work for the editor. My codes are as follows.

my route

Route::prefix('')->namespace('Web')->name('')->group(function() {
    Route::post('/upload', 'UploadController@index' )->name('index');
});

my UploadController.php

class UploadController extends Controller
{
    public function index(Request $request)
    {
        $file = $request->file('file');
        $file->move( storage_path('uploads') , imagetrim($file->getClientOriginalName()) );
    }
}

my blade:

<textarea name="content" class="editor"></textarea>

my js:

var editor = new Jodit('.editor', {
    textIcons: false,
    iframe: false,
    iframeStyle: '*,.jodit_wysiwyg {color:red;}',
    height: 800 ,
    defaultMode: Jodit.MODE_WYSIWYG,
    observer: {
        timeout: 100
    },
    commandToHotkeys: {
        'openreplacedialog': 'ctrl+p'
    },
    uploader: {
        url: '/upload'
    },
    });
});

Error Console:

1. Uncaught (in promise) TypeError: resp is undefined.
2. Post : http://127.0.0.1:8000/upload :> Status: 500 Internal Server Error

But I am not getting a good result, I can't upload, and the photo is not uploaded to the folder storage/uploads. It says that resp is not defined and you need to add it. What code should I enter for it (resp) to be uploaded?

Please help.

If you want to use file manager or other features, you have to buy it. Because it is a paid program.
