I'm using Aspose Words .Net library for many months without any problem but I'm facing an issue concerning docx file conversion to PDF file.
I simply get all bytes from the docx file, open a memorystream and give the stream to Aspose library for a PDF conversion.
The conversion step is throwing System.InvalidOperationException.
My Aspose.Words.dll version is 18.104.22.168. .Net framework version is 4.6.1.
Please find in attachment a sample project reproducing the problem.
