Error using Save

[motogeek]

Support,

All the sudden we start getting these error with our application. It's not allowing us to use the save method in our development and production.

using:

pdfDoc.SaveToFile( {path variable in our code} );

We do not need any further assistance. The developer was appending a page to the current PdfDocument, closing the PdfDocumentobject before and then when saving the PdfDocumentobject to pdf file the PdfDocument object was no longer available hence the null response from the api.

Thanks
