send data inertia to laravel controller

Question

I make a drag and drop sortable list in inertia like this :

      <draggable 
        v-model="articles.data" 
        group="people" 
        @start="drag=true" 
        @end="drag=false" 
        item-key="id"
        :component-data="getComponentData()">
        <template #item="{element}">
          <div>{{element.title}}</div>
        </template>
      </draggable>

and i want to send the result order to my laravel controller, so i try this :

function handleChange() {
  Inertia.post('/TierList/update/', props.articles.data)
}

I was thinking i will get this in my request like this :

public function update(Request $request)
{
    dd("update", $request);
}

but i have nothing. this is what my dump send :

"update"
Illuminate\Support\Facades\Request {#1122} 

I know it is probably the wrong way, but with many search i'm still screwed up, if someone can send me some tips.
