[buecherlstefan]

Version

1.50.0-beta-2

Steps to reproduce

Exception if the resulting pdf-file is greater than 512mb

        var pdfByteArray = await page.PdfAsync(new PagePdfOptions
        {
            Width = $"{options.WidthPx}px",
            Height = $"{options.HeightPx}px",
            HeaderTemplate = options.HeaderTemplateHtml,
            FooterTemplate = options.FooterTemplateHtml,
            DisplayHeaderFooter = options.DisplayHeaderFooter,
            PrintBackground = true,
            PreferCSSPageSize = true,
            Margin = new Margin
            {
                Bottom = options.Margin?.BottomPx != null ? $"{options.Margin?.BottomPx}px" : null,
                Left = options.Margin?.LeftPx != null ? $"{options.Margin?.LeftPx}px" : null,
                Right = options.Margin?.RightPx != null ? $"{options.Margin?.RightPx}px" : null,
                Top = options.Margin?.TopPx != null ? $"{options.Margin?.TopPx}px" : null
            },
        });

Expected behavior

Large PDFs (Greater than 512mb) should be generated.

Actual behavior

Exception

Cannot create a string longer than 0x1fffffe8 characters

Additional context

It looks like in playwright this issue is caused by base64. Maybe it can help to solve: https://github.com/microsoft/playwright/issues/14675
