Hi.
I’m using aspose for .NET to try to concatenate 2 PDF files, but when I run my code in windows it works correctly, but when I change to run in docker I get a 0 bytes PDF or if I set AllowConcatenateExceptions to true, I got this NullReferenceException:

I have a .NET 5 Web Api project and this is my sample code:
[HttpPost]
[DisableRequestSizeLimit]
public IActionResult ConvertDebug([FromForm] IFormFile file1, [FromForm] IFormFile file2)
{
string filepath1 = Path.GetTempPath() + Guid.NewGuid().ToString() + Path.GetExtension(file1.FileName);
using (FileStream fileStream = new FileStream(filepath1, FileMode.Create, FileAccess.Write, FileShare.None))
{
file1.CopyTo(fileStream);
}
string filepath2 = Path.GetTempPath() + Guid.NewGuid().ToString() + Path.GetExtension(file2.FileName);
using (FileStream fileStream = new FileStream(filepath2, FileMode.Create, FileAccess.Write, FileShare.None))
{
file2.CopyTo(fileStream);
}
string output = Path.GetTempPath() + Guid.NewGuid().ToString() + ".pdf";
PdfFileEditor editor = new PdfFileEditor();
editor.AllowConcatenateExceptions = true;
editor.Concatenate(filepath1, filepath2, output);
FileStream stream = new FileStream(output, FileMode.Open);
return File(stream, "application/pdf", new FileInfo(output).Name);
}
And here is my PDF files to concatenate
