I have a report that has not changed in years. This weekend, suddenly started getting this error. I won't rule out that this might not be bad data on my part, but have no idea where to go. This report is more than 1,000 pages long, it's not going to be easy to find the bad data.

I couldn't possible include all of the code here, this report is far too complex. It's crashing on the 'RenderDocument()';

PdfDocumentRenderer myRender = new PdfDocumentRenderer(true);
myRender.Document = myDocument;
myRender.RenderDocument();
myRender.Save(reportPath);

StackTrace:
at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource)
at MigraDoc.Rendering.TableRenderer.FinishLayoutInfo(Area area, XUnit currentHeight, XUnit startingHeight)
at MigraDoc.Rendering.TableRenderer.Format(Area area, FormatInfo previousFormatInfo)
at MigraDoc.Rendering.TopDownFormatter.FormatOnAreas(XGraphics gfx, Boolean topLevel)
at MigraDoc.Rendering.FormattedDocument.Format(XGraphics gfx)
at MigraDoc.Rendering.DocumentRenderer.PrepareDocument()
at MigraDoc.Rendering.PdfDocumentRenderer.PrepareDocumentRenderer(Boolean prepareCompletely)
at MigraDoc.Rendering.PdfDocumentRenderer.PrepareRenderPages()
at MigraDoc.Rendering.PdfDocumentRenderer.RenderDocument()

If we had the 1000 pages we could start searching for the cause. Without a single page I don't know where to start searching.
An MDDDL file might help us.

I worked to get it as small as I can, yet, still have the issue. Raw file is still 20 MB

I hope .rar works for you. When I used .zip it exceeded maximum size.

I found the problem!

There was one situation, where I had a table initialized, but due to a quirky logic error, I initialized it a second time, before I added the columns.

However, this for sure did happen on the old release, and the old release ignored it. This code has not changed in a long time, so PDFSharp used to handle this.

So I fixed my logic error, and I'm working fine now. It would be helpful to have a slightly more useful error message.

The DDL does show that I have a table with no columns or rows.
