I found some errors in debug mode

OC\Files\View::__construct(): Argument #1 ($root) must be of type string, null given, called in /srv/www/html/nextcloud.ad-computing.fr/apps/workflow_pdf_converter/lib/BackgroundJobs/Convert.php on line 76

Line 68 I added the code below

 67                 $pathSegments = explode('/', $path, 4);
 68                 $dir = dirname($path);
 69                 $file = basename($path);
 70
 71                 Filesystem::init($pathSegments[1], '/' . $pathSegments[1] . '/files');
 72                 try {
 73                         $node = $this->rootFolder->get($path);
 74                 } catch (NotFoundException $e) {
 75                         return;
 76                 }
 77                 $view = new View($dir);

Then I got an other error when I created a new file

could not convert /adcomput/files/test1 - Copie.docx, reason: []
