Model::withCount('relation') throws "Array to string conversion"

[znittzel]

When using Laravels "withCount" on a models relation it returns the error:

Array to string conversion in HasOneOrMany.php line 412

. Im not sure why this error is thrown in

Illuminate/Database/Eloquent/Relations/HasOneOrMany.php

when NeoEloquent has its own HasOneOrMany -class. Maybe i've set up the model incorrectly:

namespace App;

use Vinelab\NeoEloquent\Eloquent\Model as NeoEloquent;

class Event extends NeoEloquent
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'title',
        'price',
        'picture',
        'currency',
        'date',
        'from_time',
        'to_time',
        'geolocation',
        'city',
        'description',
        'age_limits',
        'is_private'
    ];

    /**
     * Label in graph db
     */
    protected $label = "Event";

    /**
     * The host (user) of this Event
     */
    public function host() {
        return $this->hasOne('App\User', 'host');
    }

    /**
     * Guests of this Event
     */
    public function guests() {
        return $this->belongsToMany('App\User', 'going_to');
    }

    /**
     * Invited users through Invite
     */
    public function has_invites() {
        return $this->hasMany('App\Invite', 'has');
    }
}

And the query

// Get all public events with count of guests
$events = Event::whereIs_private(false)->withCount('guests')->get();

Have the same problem, just for the other edge direction.

ErrorException in BelongsTo.php line 102:

Any ideas?

I became a part of Neo's Slack-channel and asked generally about using "with". I got a reply that "with" is not ment to work more than including a related model, like so Model::with('subModel')->get(). Right now I'm going the long way of counting the objects in my code, which gives me an extra call to the db. Although, I saw while debugging in the neoEloquent that the framework itself is doing an extra call anyway when using "with" so maybe there's no better solution.
