Snapshot Missing - View Column with Livewire Component

Evening! After some wisdom from you smart people! I have a table defined on my PlayerResource with a ViewColumn that had a custom view;

public static function table(Table $table): Table
    {
        return $table
            ->columns([
                ViewColumn::make('username')
                ->label('Player')
                ->searchable()
                ->sortable()
                ->view('admin.players.columns.username'),
                TextColumn::make('last_login_at')
                ->label('Last Login')
                ->sortable(),
            ]);
    }

public static function table(Table $table): Table
    {
        return $table
            ->columns([
                ViewColumn::make('username')
                ->label('Player')
                ->searchable()
                ->sortable()
                ->view('admin.players.columns.username'),
                TextColumn::make('last_login_at')
                ->label('Last Login')
                ->sortable(),
            ]);
    }

Within the custom view I am calling a Livewire Component as seen below

  @livewire('player-avatars', ['uuid' => $getRecord()->minecraft_uuid], key("player-{$getRecord()->id}"))

  @livewire('player-avatars', ['uuid' => $getRecord()->minecraft_uuid], key("player-{$getRecord()->id}"))

This is the Livewire Component content

<?php

namespace App\Livewire;

use Livewire\Component;
use App\Helpers\MinecraftHelper;

class PlayerAvatars extends Component
{
    public $uuid;
    public $avatar;

    public function mount($uuid)
    {
        $this->uuid = $uuid;
        $this->avatar = '/storage/avatars/steve.png';
    }

    public function loadAvatar()
    {
        // Load the real avatar asynchronously
        $this->avatar = MinecraftHelper::getPlayerHead($this->uuid);
    }

    public function render()
    {
        return view('livewire.player-avatars');
    }
}

<?php

namespace App\Livewire;

use Livewire\Component;
use App\Helpers\MinecraftHelper;

class PlayerAvatars extends Component
{
    public $uuid;
    public $avatar;

    public function mount($uuid)
    {
        $this->uuid = $uuid;
        $this->avatar = '/storage/avatars/steve.png';
    }

    public function loadAvatar()
    {
        // Load the real avatar asynchronously
        $this->avatar = MinecraftHelper::getPlayerHead($this->uuid);
    }

    public function render()
    {
        return view('livewire.player-avatars');
    }
}

<div>
    <img wire:init="loadAvatar" src="{{ $avatar }}" alt="Player Avatar" class="relative w-9 h-9 mx-3 rounded-md" width="36" height="36">
</div>

<div>
    <img wire:init="loadAvatar" src="{{ $avatar }}" alt="Player Avatar" class="relative w-9 h-9 mx-3 rounded-md" width="36" height="36">
</div>

It works perfectly for the most part however I noticed that when I have per page as all, change it down to a smaller amount like 10, go to the next page and change it back to all it will fail to get and display the avatars from the page I had just been on. I recieve the error Uncaught Snapshot Is this something im doing or a limitation in filament? After any guidance! See screen recording for demonstration 🙂

Oops forgot the screen recording!

Still trying to figure out what is up. Other issues with similar errors give a potential fix by using wire:key however I have; @livewire('player-avatars', ['uuid' => $getRecord()->minecraft_uuid, key('player-avatar-' . $getRecord()->id) Unsure how to fix at this stage :/

The Problem: I was facing an issue where Livewire components were not rendering correctly when changing the pagination state of a Filament table. Specifically, when I switched from page 2 to 'all' records, the avatars for some records weren't loading properly. The Solution: After diving into the Livewire and Filament documentation, I realised the problem was with how Livewire handles dynamic components. The key was to make each Livewire component instance unique for every render, especially when pagination states change. I used Livewire’s wire:key directive to uniquely identify each instance of my player-avatars component. The key was to include the current pagination page number in the wire:key attribute. This way, every time the page number changes, Livewire knows to re-render the component.

@livewire('player-avatars', ['uuid' => $getRecord()->minecraft_uuid, 'class' => 'w-9 h-9 mr-3 rounded-md'], key('player-avatar-' . $getRecord()->id . '-' . $this->getTableRecords()->currentPage()))

@livewire('player-avatars', ['uuid' => $getRecord()->minecraft_uuid, 'class' => 'w-9 h-9 mr-3 rounded-md'], key('player-avatar-' . $getRecord()->id . '-' . $this->getTableRecords()->currentPage()))

By appending getTableRecords()->currentPage() to the wire:key, each avatar component is now tied not only to the record's ID but also to the current page number. This ensures proper re-rendering when the pagination state changes. Why This Works: Livewire needs to uniquely identify each component instance to manage its lifecycle effectively, especially when dealing with dynamic content like pagination. By adding the current page number to the wire:key, we help Livewire understand when it needs to refresh the components, ensuring our UI stays in sync with our application's state. Hope this helps anyone who might be facing similar issues. 🚀

@Josh excuse me for tagging u josh, facing similar issue, but in my case, i display three different livewire components passed to viewfields in resource view. The behaviour was whenever i click on a page action or change relationmanager tabs, the last rendered component disappear and I received the same uncaught snapshot error. Do you perhaps have any clue on figuring this out? Again sorry.
