Ok, I have simplified the code and have it to where if you run this code in .net core with 6.1.1, you will get the error I have having. There are no database looks, so everything you need to reproduce the error is here:
Color MuellerBlue = new(0, 44, 115);
Document PDFDoc = new();
Document TempDoc = new();
Section Page1Section = PDFDoc.AddSection();
Table MainTable = Page1Section.AddTable();
PageSetup DocumentSetup = PDFDoc.DefaultPageSetup.Clone();
DocumentSetup.Orientation = Orientation.Portrait;
DocumentSetup.PageHeight = Unit.FromInch(11);
DocumentSetup.PageWidth = Unit.FromInch(8.5);
DocumentSetup.TopMargin = Unit.FromInch(.75);
DocumentSetup.HeaderDistance = Unit.FromInch(.25);
DocumentSetup.LeftMargin = Unit.FromInch(.5);
DocumentSetup.RightMargin = Unit.FromInch(.5);
DocumentSetup.BottomMargin = Unit.FromInch(.75);
DocumentSetup.FooterDistance = Unit.FromInch(.25);
DocumentSetup.DifferentFirstPageHeaderFooter = true;
Paragraph PageNumberParagraph = new Paragraph();
HeaderFooter footer = Page1Section.Footers.Primary;
Style TitleStyle = new("TitleStyle", "Normal");
TitleStyle.Font.Name = "Georgia";
TitleStyle.Font.Bold = true;
TitleStyle.Font.Color = MuellerBlue;
TitleStyle.Font.Size = Unit.FromPoint(16);
PDFDoc.Add(TitleStyle);
int PageCount = 1;
int BlockCounter = 0;
///this is a simplified version of the code I am running.
///the comments to the right indicate the line number in the code to make it easier for me to refer too.
MainTable.AddColumn(Unit.FromInch(6));
Row myrow = MainTable.AddRow();//added to give myrow a definition; not in original code.
Paragraph paragraph = myrow.Cells[0].AddParagraph();
