Laravel-mongodb: Type error: Argument 1 passed to Jenssegers\Mongodb\Query\Builder::__construct() must be an instance of Jenssegers\Mongodb\Connection, instance of Illuminate\Database\MySqlConnection given

Methods like firstOrCreate, firstOrNew don't work on laravel 5.4.
When calling them i get this error:

Type error: Argument 1 passed to Jenssegers\Mongodb\Query\Builder::__construct() must be an instance of Jenssegers\Mongodb\Connection, instance of Illuminate\Database\MySqlConnection given,

I've found a workaround, which should be fixed in the package itself. The problem was when calling

Illuminate\Database\Eloquent::resolveConnection($connection = null)

and passing null, because DatabaseManager just took the default connection in this case.
My fix was extending this method in my model and hardcoding the connection name inside it.

    /**
     * Resolve a connection instance.
     *
     * @param  string|null  $connection
     * @return \Illuminate\Database\Connection
     */
    public static function resolveConnection($connection = null)
    {
        return static::$resolver->connection('mongodb');
    }

Just setting

    protected $connection = 'mongodb';

doesn't work. I've tried setting it through __construct(), calling $this->setConnection() and some other stuff, but it still wouldn't work. It probably gets overwritten somewhere.

I just might be missing something extremely obvious.

I had the same Issue today and remembered the .env file which overrides the config files.
Maybe this will fix it for you too!

Hello here is an example that works with us.

<?php

namespace App;

//use Jenssegers\Mongodb\Eloquent\Model;
use Illuminate\Database\Eloquent\Model;
use Jenssegers\Mongodb\Eloquent\HybridRelations;

class Profil extends Model
{

    use HybridRelations;

    protected $connection = 'mysql';

    public function adresses(){
        return $this->hasMany("App\Adresse",'profils_id');
    }
}
