Cannot upload file: (file name), Ckeditor 5 Laravel - php

Question

Help :(, I'm a newbie trying out CKeditor 5 for my post form
I'm using ckeditor 5, and i'm trying to upload images in it. But, when i'm trying to load image i have a massage: Cannot upload file filename.
Where's the problem?
Init function :
ClassicEditor
.create( document.querySelector( '#body' ), {
ckfinder:{
uploadUrl: "{{ route('ckeditor.upload') .'?token=' . csrf_token()}}"
}
} )
.catch( error => {
console.error( error );
} );
PHP config :
$config['backends']['default'] = array(
'name' => 'default',
'adapter' => 'local',
'baseUrl' => config('app.url').'/userfiles/',
'root' => public_path('/userfiles/'),
'chmodFiles' => 0777,
'chmodFolders' => 0755,
'filesystemEncoding' => 'UTF-8'
);
Controller :
public function uploadImage(Request $request){
if($request -> hasFile('upload')){
$originame = $request->file('upload')->getClientOriginalName();
$fileName = pathinfo($originame, PATHINFO_FILENAME);
$extension = $request->file('upload')->getClientOriginalExtension();
$fileName = $fileName . '_' . time() . '.' . $extension;
$request->file('upload')->move(public_path('media'), $fileName);
$url = asset('media/' . $fileName);
return response()->json(['fileName' => $fileName, 'uploaded'=> 1, 'url' => $url]);
}
}
Thank you, help me :')
