converting DNG image to jpeg failing

[icorderosss]

I'm getting this error when I try to mount my dng image
'Unsupported file format or not RAW file (DNG Path)
this is my code
`

public static string IOSImageConverter(ServiceTicketDocument doc)
{
string jpegPath = Path.ChangeExtension(doc.FileFullPath, ".jpeg");
//it fails on the using
using (var image = new MagickImage(doc.FileFullPath))
{
image.Format = MagickFormat.Jpeg;
using (MemoryStream ms = new MemoryStream())
{
image.Write(ms);
byte[] imgData = ms.ToArray();
doc.DocumentObject= imgData;
doc.DocumentObjectType="jpeg";
doc.FileFullPath = jpegPath;
doc.Update();
}
image.Write(jpegPath);
}
return doc.FileFullPath;
}

Can you share your file so I can give an answer why it is not supported? You can find my email on my profile in case you cannot share it publicly.

I wish I could, but it has sensitive client information.
