Why livewire component lost event subscription

My livewire component lost event subscription and I don't know why ((

Event publisher code:

use Livewire\Component;

class NodeCollapse extends Component
{
public function toggleCollapsed(): void
{
$this->dispatch('node.collapse', [
'node' => $this->id,
'collapse' => $this->collapsed,
]);
}

}


JavaScript subscriber:

document.addEventListener('node.collapse', (event) => {
console.log('node.collapse', event)
})


This subscriber works good - event with packed data got on front.

Then Livewire subscriber:

use Livewire\Component;
use Livewire\Attributes\On;

class Node extends Component
{
#[On('node.collapse')]
public function applyCollapse(mixed $data)
{
...
}
}



This subscriber not catching event (( . Few days ago this code worked well, but for now something happened and it don't.

What's wrong?
