I get an error when trying to update my user model when using the RevisionableTrait

[lnieuwenhuis]

Relevant part of the user model:

<?php

namespace App\Models;

use App\Enum\RoleEnum;
use App\Observers\UserObserver;
use App\Scopes\UserScope;
use Illuminate\Database\Eloquent\Attributes\ObservedBy;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;
use Spatie\Permission\Traits\HasRoles;
use Venturecraft\Revisionable\RevisionableTrait;

#[ObservedBy([UserObserver::class])]
class User extends Authenticatable
{
    use HasApiTokens;
    use HasFactory;
    use HasRoles;
    use Notifiable;
    use SoftDeletes;
    use RevisionableTrait;

Error I get from RevisionableTrait when trying to update anything on any user:

Somehow the event function is broken. I haven't dug too deep into the code, but I don't really have any time to do so.

As a side-note, here is the part of the RevisionableTrait that is causing the error:

public function postSave()
    {
        if (isset($this->historyLimit) && $this->revisionHistory()->count() >= $this->historyLimit) {

            }
        }
    }

All the way at the bottom, the

                \Event::dispatch('revisionable.saved', array('model' => $this, 'revisions' => $revisions));

Is where it goes wrong

Remove the \ before the Event. If you are still getting errors, additionally add the following to the top of the file:

use Illuminate\Support\Facades\Event;

I hope this helps!
