FTP UPLOAD FILE Laravel - laravel

Question

I try to send an excel file who was created when i refresh the page. I used the package https://github.com/harishanchu/Laravel-FTP
When i run the code bellow i get an exception like :
pathinfo() expects parameter 1 to be string, array given
I don't want to pick up a file in the storage because the system that i made will run the daily query everyday and send the file via FTP ! so i can't know the path before the file was created.
Hope someone could help me on this ! thanks a lot in advance
here the full code :
$licencies = Licencies::where('lb_assurance' , '=' , 'Lafont')
->leftJoin('activite_licencie' , 'activite_licencie.id' , '=' , 'licencies.activite_licencie_id')
->leftJoin('saisons' , 'saisons.id' , '=' , 'licencies.saison_id')
->leftJoin('pays' , 'pays.id' , '=' , 'licencies.pays_naissance_id')
->leftJoin('type_licence' , 'type_licence.id' , '=' , 'licencies.type_licence_id')
->leftJoin('structures' , 'structures.id' , '=' , 'licencies.structure_id')
->leftJoin('civilite' , 'civilite.id' , '=' , 'licencies.civilite_id')
->leftJoin('catg_licence' , 'catg_licence.id' , '=' , 'licencies.catg_licence_id')
->select('num_licence' , 'civilite.lb_civilite' , 'lb_nom' , 'lb_prenom' , 'dt_naissance' , 'pays.fr' ,'activite_licencie.lb_activite' , 'catg_licence.lb_catg_lic' , 'type_licence.lb_type' ,'saisons.lb_saison', 'lb_surclassement' , 'structures.nom_structure' , 'lb_assurance' , 'cd_dept_naissance' , 'lb_adresse' , 'tel_fix_licencie' , 'tel_port_licencie' , 'adresse_email')
->whereRaw('DATE(licencies.created_at) = CURRENT_DATE')
->get();
$licencies->map(function($licencie) {
$licencie['dt_naissance'] = \Carbon\Carbon::parse($licencie['dt_naissance'])->format('d/m/Y');
//$licencie['created_at'] = \Carbon\Carbon::parse($licencie['created_at'])->format('d/m/Y H:i:s');
return $licencie;
});
$date = Carbon::now('Europe/Paris')->format('d-m-Y H:i:s');
$file = Excel::create('Assurance Lafont - Saisie des Licences FFRXIII le : ' . $date . '' , function($excel) use ($licencies) {
$excel->sheet('Excel', function($sheet) use ($licencies)
{
$sheet->fromArray($licencies);
});
});
$directory = 'mydirectory' ;
$ftp = FTP::connection()->uploadFile($file, $directory);
dd($ftp);
