<div id="<?php echo e($id); ?>" x-data="{ show: <?php if ((object) ($attributes->wire('model')) instanceof \Livewire\WireDirective) : ?>window.Livewire.find('<?php echo e($_instance->id); ?>').entangle('<?php echo e($attributes->wire('model')->value(

This was causing me much angst too but I think I found the solution: as @georgy-malanichev says, you can only call Livewire methods from inside a Livewire component (and not from inside a Blade component or any other custom components).

Given you are trying to use the component inside resources/views/dashboard.blade.php , the solution is to:

1. create a livewire component using artisan make:livewire MyDashboard
2. Cut everything between <x-app-layout> and </x-app-layout> in dashboard.blade.php and paste it into views/livewire/my-dashboard.blade.php
3. Add @livewire('my-dashboard') inside the x-app-layout tags and Bob's your uncle (it should start working)

To help you understand what's going on, if you look at the source code for the modal component, you'll see a line like: show: @entangle($attributes->wire('model')), . I'm not sure how to describe exactly what this does, but, essentially, @entangle() is expecting an instance of the "model" Livewire object and it's not finding one.

It's not finding it because it's getting called from a non-livewire component. Once you put it inside a Livewire component, it starts working.

I hope the additional details makes things clearer.

I was getting the same error but in my case it was the fact that I had x-data="{ open: @entangle('showDropdown') }" outside of the LiveWire component. Once I moved it inside the component template, where it should be, the issue went away.
