Question

I am getting below exception after deploying HTML to PDF functionality in Azure Web App(.net Framework 4.8).Same is working fine in local .

I have already added dependent nuget IronPdf.Native.Chrome.Windows as suggested. Below is the code :

var renderer = new ChromePdfRenderer();
 renderer.RenderingOptions.RenderDelay = Convert.ToInt32(SiteSettingsPage.Settings.PDFRenderDelay);
                renderer.RenderingOptions.MarginTop = 12;
                renderer.RenderingOptions.MarginBottom = 12;
                renderer.RenderingOptions.MarginLeft = 0;
                renderer.RenderingOptions.MarginRight = 0;
                renderer.RenderingOptions.PaperOrientation = 
                IronPdf.Rendering.PdfPaperOrientation.Portrait;
                renderer.RenderingOptions.PaperSize = IronPdf.Rendering.PdfPaperSize.A4;
 var pdf = renderer.RenderUrlAsPdf(htmlFileUrl).BinaryData;

Does you application run on build machine in both Debug and Release folders? When you deploy it is using the Release folder on build machine. You may be running successfully with debug on build machine. Check the dates in the bin folder of project and see if the Debug and Release executable are current. — jdweng, Apr 05 '23 at 09:50
Make sure your packages are updated. Use the latest versions. — Harshitha, Apr 05 '23 at 10:38
Are you deploying to Azure `Windows` or `Linux` App Service ? — Harshitha, Apr 05 '23 at 10:44

As per the above requirement I have reproduced from my end I tried your code it works fine in local but where as deployed in webapp it was showing error.

Thanks @jdweng for your suggestions in the comments. Below is the code which I tried to reproduce.

        var renderer = new ChromePdfRenderer();
        var pdf = renderer.RenderHtmlAsPdf(File.ReadAllText(htmlFilePath));
        pdf.SaveAs(pdfFilePath);

        Console.WriteLine($"PDF saved to {pdfFilePath}");
        Console.WriteLine("Conversion complete!");

        var credentials = SdkContext.AzureCredentialsFactory.FromFile("azureauth.properties");
        var azure = Azure.Configure().WithLogLevel(HttpLoggingDelegatingHandler.Level.Basic).Authenticate(credentials).WithDefaultSubscription();
        var webApp = azure.WebApps.GetById("resource-group-name", "webapp-name");

        using (var fileStream = new FileStream(pdfFilePath, FileMode.Open))
        {
            webApp.Inner.WebApps.CreateOrUpdateSiteBlobSource("wwwroot", "pdf-file-name.pdf", fileStream);
        }

        Console.WriteLine($"PDF uploaded to {webApp.DefaultHostName}/pdf-file-name.pdf");
    }
}

In the above code SdkContext.AzureCredentialsFactory.FromFile method to read your Azure credentials from a file called "azureauth.properties" that should be located in the same directory as your program file.
azure.WebApps.GetById method retrieves an instance of your web app using the resource group and web app names.
FileStream object to read the contents of the PDF file, and then use the webApp.Inner.WebApps.CreateOrUpdateSiteBlobSource method to create or update a blob in the web app's root directory
