You seem to be mixing full page component with component. For a regular component you need to pass the id

Unable to resolve dependency [Parameter #0 [ <required> $id ]] in class App\Http\Livewire\Blog\ShowPost
When I want to render the ShowPost component I faced this error
this is the route:
Route::get('/blog/{id}', function () { return view('pages/show-post'); })
this is the show-post.blade.php
@extends('pages.ShowLayout')
@section('content')
<header class="header-image ken-burn-center light" data-parallax="true" data-natural-height="1080" data-natural-width="1920" data-bleed="0" data-image-src="http://via.placeholder.com/1920x1080" data-offset="0" style="margin-top: 120px;">
<div class="container" style="margin-top: 0px; opacity: 1;">
<h1>{{ __("The Blog")}}</h1>
<h2>{{__("The best view comes after hardest climb")}}</h2>
<ol class="breadcrumb">
<li><a href="index.html">{{__('Home')}}</a></li>
<li><a href="#">{{__("Pages")}}</a></li>
<li><a href="#">{{__("Blog")}}</a></li>
</ol>
</div>
</header>
<main>
<section class="section-base section-color">
<div class="container">
<div class="row">
@livewire('blog.show-post')
@livewire('blog.categories')
</div>
</div>
</section>
</main>
and this is the component Class:
class ShowPost extends Component { public $post; public $local;
public function mount($id){
$this->local = app()->getLocale();
$this->post = Blog::find($id);
}
public function render()
{
return view('livewire.blog.show-post')
->extends('pages.ShowLayout')
->section('content');
}
}

I used it like this:
@livewire('blog.show-post', ['id' => $id])
and now it shows:
Undefined variable: id (View: C:\xampp\htdocs\Hikeventure\resources\views\pages\show-post.blade.php)

You need to pass it to the view
Route::get('/blog/{id}', function ($id) { return view('pages/show-post', compact('id') ); })

Use dd() to debug your code. Check if you get a proper id
public function mount($id){
dd($id);
$this->post = Blog::find($id);
dd($this->post);
$this->local = app()->getLocale();
}

I have the same problem and i cant fix it, I get error:
Unable to resolve dependency [Parameter #1 [ <required> $action ]]
i have a simple button like this : wire:click="success ({{ $service->id }},0)"
And a simple function :
public function success($serviceID,$action)
{
$data = [
'success' => $action,
];
service::find($serviceID)->update($data);
}
the data passing correctly through the query, but i get that error and after refresh the page i can see the updated data, i cant find solution.

Upgrade this function
public function success($serviceID=null,$action=null)
{
$data = [
'success' => $action,
];
service::find($serviceID)->update($data);
}
my functions like this
function save($key = null)
{
$item = @$this->items[$key];
if ($item) {
Trans::where('id', $item['id'])->update(['value' => $item['value']]);
$this->emit('toast', AcrTrans('Update success'), 'success');
}
}
