Getting Gateway Timeout Error when Converting PPTX to PDF

On Slides I am frequently getting Gateway Timeout Error on some files, does it have to do something with size? as most common culprits are PPTX with more than 100 slides.

And Aspose API logs show status 200 for the API call

Thank you for contacting support.

To investigate the case and help you, we need more details. Please share the following files and information:

  • sample presentation file (you can share a link to the file saved in a file storage such as Google Drive, Dropbox, etc.)
  • code example that reproduces the error
  • Aspose.Slides Cloud API version you are using

Please also note that you can use asynchronous conversion API for large files.

public function powerpointToPDF($file, $phone, $code)
        $config = new Configuration();

        $api = new SlidesApi(null, $config);

        $result = $api->Convert(
                "storage/app/public/WhatsApp_Files/" . $phone . "/" . $file,


        if (
            !File::isDirectory(public_path("/storage/WhatsApp_Files/" . $phone))
        ) {
                public_path("/storage/WhatsApp_Files/" . $phone),

                "storage/WhatsApp_Files/" . $phone . "/" . $code . ".pdf"

        $name = asset("public/storage/WhatsApp_Files/$phone/$code.pdf");

        return $name;
