Hi, I setup the workflow that all office documents are automatically converted into PDF on my nextcloud instance, and it was working since several years. After upgrading to NC 33.0 PDF files are no longer created.

The logfile says:

I have no idea what is going wrong here after the update.

Hi, I think I git it back running. I checked the content of the file nextcloud/apps/workflow_pdf_converter/lib/BackgroundJobs/Convert.php and checked the content with the previous version.

I saw that one line $dir = dirname($path); was removed in line 64 after $PathSegments:

            $pathSegments = explode('/', $path, 4);
            $dir = dirname($path);
            $file = basename($path);

After adding it back the PDF are now created back automatically via cron.
