“试图获取非对象的属性 'id'” Laravel - Auth::id() 命令

Question

This is a sample of my code from DatatablesController.php

$id = Auth::user()->id;
   $data = Cdr::
      select('src','dst','start','duration','billsec','disposition','uniqueid')
      ->where('billsec','>', '0')
      ->where('start','>=',Carbon::today())
      ->join('alt_portal.numbers', 'nr','=','dst') 
      ->where('alt_portal.numbers.user_id','=',$id)
      ->get(); 

I am doing Laravel project in which will be a lot of users. And each user has it's own number or numbers. Basically, I am trying to select from database only those numbers which belong to specific user, in other words, to logged in user's ID, because user can only see his/her outgoing and incoming calls in the table.

And when I am trying to do this:

$id = Auth::user()->id;
...
->where('alt_portal.numbers.user_id','=',$id)

I get a message in browser, which corresponds to an error:

message: "Trying to get property 'id' of non-object"

Does anyone know how to correct this issue?

PS I am new to Laravel.

Case closed. Thank you guys for you responses. I managed to fix my problem.

I found solution here: ANSWER But I added stack directly to middleware, not in the 'web' group.

This is my /Http/kernel.php file:

protected $middleware = [
        \Illuminate\Session\Middleware\StartSession::class,
        \App\Http\Middleware\TrustProxies::class,
        \App\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class
    ];
