XPS to PDF File conversion is failing using Aspose.PDF

Hello Aspose Team,

We have licensed Aspose.pdf and Aspose.words.

At local machine - When I run the application at local and then able to convert xps and oxps file into pdf. But When we deployed our git project into AWS (lambda on AWS and in a Linux container image) then it is failing while converting the xps or oxps fil into pdf.
Getting following issue - When trying to convert xps or oxps file into pdf.

Error (XPS file conversion to pdf is failed and throwing an error):
“Error Log FunctionHandler Exception:[System.AggregateException: One or more errors occurred. (Supplied XPS file or stream is corrupt and cannot be parsed!) —> System.IO.FileLoadException: Supplied XPS file or stream is corrupt and cannot be parsed!”

Note: This is implemented at .Net Core with AWS Lambda.

Via Nuget Package Manager console installed - Aspose.PDF version 23.5.0
And also installed Aspose.words 21.11.0

At this .net core application lambda - We are using both Aspose words and pdf licensed libraries.

Also included both .lic files

Aspose.PDF.NET.lic

aspose.words.net.lic

At a class file - Constructor set license

        Aspose.Words.License license = new Aspose.Words.License();
        license.SetLicense(@"aspose.words.net.lic");

        Aspose.Pdf.License pdflicense = new Aspose.Pdf.License();
        pdflicense.SetLicense(@"Aspose.PDF.NET.lic");

Technical Details:

Failing at this line of code document.Save(stream, Aspose.Pdf.SaveFormat.Pdf);

This is code block

var document = new Aspose.Pdf.Document(fileStream, new Aspose.Pdf.XpsLoadOptions());

        using (MemoryStream stream = new MemoryStream())
        {
            document.Save(stream, Aspose.Pdf.SaveFormat.Pdf);                

            LoggerService.Log($"Start Save the file to pdf [{filePath}]");
            
            var status = false;
            try
            { 
                // Place the pdf file at AWS S3 bucket
                PutObjectRequest request = new PutObjectRequest()
                {
                    AutoCloseStream = true,
                    BucketName = bucketName,
                    Key = key,
                    InputStream = stream,
                    ContentType = "application/pdf"
                };

                var response = await _s3Client.PutObjectAsync(request);
                status = (response.HttpStatusCode == HttpStatusCode.OK);
            }
            finally
            {
                if (stream != null)
                {
                    stream.Close();
                    stream.Dispose();
                }
            }
        }
