Error: Sequence contains no elements when running DocumentBuilder on a server

[DeuteriumCore]

However, when I run part of the code that merges two documents on my computer, it works fine. Any help? Thanks!

Here is the code: `using (WordprocessingDocument wDocIn = WordprocessingDocument.Open(mem, false)) using (WordprocessingDocument wDocTemplate = WordprocessingDocument.Open(mem2, false)) { List sources = new List();

                WmlDocument wmlIn = new WmlDocument("", mem);
                WmlDocument wmlTemplate = new WmlDocument("", mem2);

                sources.Add(new Source(wmlIn, true));
                sources.Add(new Source(wmlTemplate, true));

                wmlIn = DocumentBuilder.BuildDocument(sources);

                Output = wmlIn.DocumentByteArray;
            }`

Unfortunately, I cannot debug the program uploaded on the server since it's . . . OutSystems.
