With Eloquent is not bringing any value

I'm using Laravel 5.2, I'm trying to 'join' n to m with 'With' from 'Eloquent' but it does not return any value even though they exist in the database.

Class Person:

class Pessoa extends Authenticatable {
    const CREATED_AT = null;
    const UPDATED_AT = null;

    protected $table = 'pessoa';
    public $primaryKey = 'idPessoa';
    public $incrementing = false;

    public function Perfis(){
        return $this->hasMany(Perfil::class, 'idPessoa', 'idPessoa');
    }

}

class Perfil extends Model {
    const CREATED_AT = null;
    const UPDATED_AT = null;

    protected $table = 'perfil';
    public $primaryKey = 'idPerfil';
    public $incrementing = false;

}

Requisition Used:

dd( Pessoa::with("Perfis")->has("Perfis")->first()->Perfis );

Result:

Collection {#341 ▼
   #items: []
}

I used 'DB :: enableQueryLog ();' to get the SQLs used.

array:2 [▼
    0 => array:3 [▼
        "query" => "select * from "pessoa" where exists (select * from "perfil" where "perfil"."idPessoa" = "pessoa"."idPessoa") limit 1"
        "bindings" => []
        "time" => 2.42
    ]
    1 => array:3 [▼
        "query" => "select * from "perfil" where "perfil"."idPessoa" in (?)"
        "bindings" => array:1 [
             "0"=>"1"
        ]
        "time" => 1.33
    ]
]

If I run the Second SQL I get the Profiles list correctly. What will be the problem then?
