Image field inside json field

I am trying to use an image field inside the json field but it seems is not working, any ideas?
here is my code:
`Image::make('Image')
    ->path('entries/'.$this->model()->hash_id)
    ->acceptedTypes('image/*')
    ->storeAs(function ($request) {
          return  $request->file('metadata->entries.image')->getClientOriginalName();
        })
    ->disk(config('filesystems.default')),`
