у нас есть asp.net веб-приложение core 3.0.

Некоторые представления также отображаются в формате PDF.

Мы используем Rotativa, отличную библиотеку для создания pdf в Интернете.

Затем из этого кода:

 return new ViewAsPdf("TicketPdf", ticketRicambio, dict)
                {
                    FileName = "DDT Ticket n. "   ticketConRicambi.TicketAssistenza.IdTicket.ToString()   ".pdf",
                    PageSize = Rotativa.AspNetCore.Options.Size.A4,
                    CustomSwitches = customSwitches,
                    MinimumFontSize =
                        Convert.ToInt32(dimensioneTestoRotativa),
                    PageMargins =
                    {
                        Right = Convert.ToInt32(margineRightRotativa),
                        Left = Convert.ToInt32(margineLeftRotativa),
                        Top = Convert.ToInt32(margineTopRotativa) ,
                        Bottom = Convert.ToInt32(margineBottonRotativa)
                    }
                };
 

у нас есть это исключение:

Пожалуйста, кто-нибудь может помочь нам справиться с этим?

Заранее спасибо.
