Upload an image via a Livewire child component

Hello,

I have a form in a Livewire component. In this form, I include a Livewire component to manage the upload of an image.

In my child controller I emit an event when the image is uploaded.

And here in my child component in which I emit an event when the image is uploaded.

public function updatedImage()
{
    $this->deleteImage = false;
    $this->url = $this->image->temporaryUrl();
    $this->uploadedImageTempUrl = $this->image->temporaryUrl();
    $this->emitUp('mediaUpdated', $this->image);
}

In my parent component view.

@livewire('upload-image')

In my parent component controller.

protected $listeners = ['mediaUpdated' => 'setMedia'];

public function setMedia($media)
{
    $this->publisher->logo = $media;
	dd($this->publisher->logo);
}

The dd() is not an file object but a simple array.

array:1 [▼
  "disk" => "local"
]

While in my child component a dd($media) gives this.

Livewire\TemporaryUploadedFile {#1217 ▼

I don't understand why ... I'd like to save the image from the parent component. But it's perhaps not the best pratice.

What do you suggest me ?

Thanks for you help ;).
