Attempt to read property "name" on null or Attempt to read property "email" on null

Good Day, could someone help or explain to me why I am getting this error when I call a livewire component?

Note: I didn't code the error locations. It's from the laravel default component files

Route:

Route::get('/post',Posts::class);

Class:

namespace App\Http\Livewire;

use Livewire\Component;

class Posts extends Component
{
    public function render()
    {
        return view('livewire.posts');
    }
}

View:

<div>
    This is a post
</div>

Error file location: resources\views\layouts\navigation.blade.php

Auth::user()->name
Auth::user()->email

The error "Attempt to read property 'name' on null" is usually caused by trying to access a property of a null object. In this case, it seems like there might be some code in your Livewire component that is trying to access a property called "name" on a null object.

To fix this error, you should check your Livewire component code and make sure that you are not trying to access any properties on null objects. You can use the null coalescing operator (??) to provide a default value for a property if it is null.

For example, if you have a property called "name" that might be null, you can access it like this:

$name = $this->someObject->name ?? 'Default Name';

This will set the $name variable to the value of $this->someObject->name if it is not null, or to 'Default Name' if it is null.

In your specific case, however, it seems like the error is not related to any property called "name". Instead, it might be caused by some other code that you have not included in your question. If you can provide more information about the error message and where it is occurring, we might be able to help you better.

Applied

Auth::user()?->name
Auth::email()?->name

And another error comes up at: resources\views\layouts\app.blade.php

Error: Undefined variable $header

{{ $header }}

Note @AungHtetPaing__: I didn't code the error locations. It's from the laravel default component files

@devianvisuals you have to pass layout data from livewire

public function render()

{

    return view('livewire.posts')

        ->layout('layouts.app', ['header' => 'header of page'])

}

laravel default layout include slot for header. so you need to pass that from livewire

It works fine now using the method:

->layout('layouts.app');
