Trait method __sleep has not been applied, because there are collisions

Question

I am trying to trigger an event whenever an user is created but but this error pops up.

<?php

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;

class NewUser
{
  use Dispatchable, InteractsWithSockets, SerializesModels;

    /**
     * Create a new event instance.
     *
     * @return void
     */

    use SerializesModels;

    public $user;

    public function __construct(App\User $user)
    {
        //
        $this->user = $user;

    }


}

I have tried searching for this __sleep function but I can't find it, and I've also tired various things with using use App\User int the top vs in the function parameter itself.

What is the issue?

This looks like its down to a typo, but should you encounter genuine conflicts: https://stackoverflow.com/questions/25064470/collisions-with-other-trait-methods — Steve, Sep 04 '17 at 19:19

You use the trait SerializesModels twice in your class definition. That causes an error, when the trait is applied a second time. __sleep() just happens to be the first method in the trait. Simplified example

Edit to add: Since you said you didn't find the __sleep() function, it's right here

Beat me to it by that much. :p – Bytewave Sep 04 '17 at 19:09
To be fair. Your comment popped up right before I pasted the link. Technically your comment was faster, but I didn't want to delete the explanation. – jh1711 Sep 04 '17 at 19:13
Actually, the reverse happened for me. Having an explanation is better anyway. – Bytewave Sep 04 '17 at 19:14
