Model::has() - ErrorException: Array to string conversion

[benargo]

Laravel version: 5.4.15
Laravel-mongodb version: 3.2.2

Issue

I've found with BelongsToMany relations calling the function Jenssegers\Mongodb\Eloquent\Model::has can throw an ErrorException with 'Array to string conversion'.

File: app/Http/Controllers/CategoriesController.php

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Models\Categories\Food;

class CategoriesController extends Controller
{
    /**
     * Returns a list of all the food categories for users to chose from.
     *
     * @return Illuminate\Http\Response
     */
    public function getFoodCategories()
    {
        $categories = Food::has('venues')->get();

        return response()->json($categories);
    }

File: app/Models/Categories/Food.php

<?php

namespace App\Models\Categories;

use Jenssegers\Mongodb\Eloquent\Model as Eloquent;

class Food extends Eloquent
{
    /**
     * The database collection used by the model.
     *
     * @var string
     */
    protected $collection = 'food_categories';

    /**
     * Adds a relationship between this and \App\Models\Venue.
     *
     * @return \Jenssegers\Mongodb\Relations\BelongsToMany
     */
    public function venues()
    {
        return $this->belongsToMany(\App\Models\Venue::class);
    }
}

File app/Models/Venue.php

<?php

namespace Genii\Models;

use Jenssegers\Mongodb\Eloquent\Model as Eloquent;

class Venue extends Eloquent
{
    /**
     * The database collection used by the model.
     *
     * @var string
     */
    protected $collection = 'venues';

    /**
     * Adds a relationship between this and \App\Models\Categories\Food.
     *
     * @return \Jenssegers\Mongodb\Relations\BelongsToMany
     */
    public function foodCategories()
    {
        return $this->belongsToMany(\App\Models\Categories\Food::class);
    }
}
