Can no longer convert AspNetZero URL to PDF using SyncFusion HtmlToPdfConverter in Core 2.2 + Angular 8 v7.1.0 #7545

Greetings Programs!

The following method works flawlessly in v7.0.0 for any url (application or external) but it breaks in v7.1.0 for any application url. It converts external urls as expected so there's nothing wrong with the conversion itself.

        public virtual void ConvertUrlToPDF(string url, string filename, string authToken = null, int minPageLoadTime = 30, string pageSize = "Letter", string orientation = "Portrait", int webPageWidth = 1024, int webPageHeight = 0, int marginTop = 20, int marginBottom = 20, int marginLeft = 20, int marginRight = 20)
        {
            var pdfPageSize = PdfPageSize.Letter;
            var pdfOrientation = (PdfPageOrientation)Enum.Parse(typeof(PdfPageOrientation), orientation, true);

            var settings = new WebKitConverterSettings
            {
                WebKitPath = Path.Combine(hostingEnvironment.ContentRootPath, "QtBinariesWindows"),
                WebKitViewPort = new Size(webPageWidth, webPageHeight),
                AdditionalDelay = minPageLoadTime * 1000,
                Margin = new PdfMargins { Left = marginLeft, Right = marginRight, Top = marginTop, Bottom = marginBottom },
                Orientation = pdfOrientation,
                PdfPageSize = pdfPageSize,
                SplitImages = false,
                SplitTextLines = true,
                TempPath = Path.GetTempPath()
            };

            if (!authToken.IsNullOrWhiteSpace())
            {
                settings.HttpRequestHeaders.Add("Authorization", $"bearer {authToken}");
            }

            //Initialize HTML to PDF converter and assign WebKit settings to HTML converter
            var htmlConverter = new HtmlToPdfConverter { ConverterSettings = settings };

            //Convert URL to PDF
            var document = htmlConverter.Convert(url);
            var stream = new MemoryStream();

            document.Save(stream);

            using (var file = new FileStream(filename, FileMode.OpenOrCreate, FileAccess.Write))
            {
                stream.WriteTo(file);
            }
        }

I generate the url and get the token from the cookie:

        let formUrl = AppConsts.appBaseUrl + '/#/app/main/form/' + this.form.formType.code.toLowerCase() + '/' + this.form.id + '/print';
        let authToken = abp.utils.getCookieValue('Abp.AuthToken');

The error is thrown by the converter:

Syncfusion.Pdf.PdfException: Failed to convert the webpage
   at Syncfusion.HtmlConverter.HtmlToPdfConverter.Convert(String url)

I'm thinking it might have something to do with the authorization header and token.

Thanks,

Wg

    Hi @ismcagdas,

    Here is the log excerpt from the moment the export method is called to the resulting SyncFusion exception.

    Is it possible to share a reproduction project via email (to [email protected]) ? It is hard to understand the problem using these logs.

    Thanks,
