Internal CLR Error (0x80131506) with HtmlToPdfConverter after upgrading to .NET 8 RC1

Hello everyone,

After upgrading from .NET 7 to .NET 8 RC, I've encountered an issue when using the HtmlToPdfConverter. The error I'm facing is an internal CLR error: (0x80131506).

Error :

Fatal error. Internal CLR error. (0x80131506)

        htmlConverter.ConverterSettings = settings;
        
        //Convert URL to PDF
        PdfDocument document = htmlConverter.Convert(html, baseUrl);

        var fileStream = new MemoryStream();
        document.Save(fileStream);
        var pdfBytes = fileStream.ToArray();
        document.Close(true);

        return pdfBytes;  
    }
}


The error wasn't present when I was using .NET 7.

Additionally, I'd like to mention that I'm facing this error when running my application inside a Docker (Linux) container as well.

Thank you in advance for your time and support.

Best regards,

Hello,


Thanks for your response.


In 'Debug' mode it works, but I get a similar problem when I activate 'Release' mode:

Hi Rémi,


Currently, We are checking the reported issue with provided details on our end and will update you further details on September 26,2023.

Karmegam

On further analysis, the reported issue occurs due to a permission-related issue in the release configuration. We are internally launching Chromium for HTML-to-PDF conversion. But we are unable to launch Chromium due to a permission issue in the release configuration environment. We can overcome this issue by adding the ‘runtimes/linux/native’ folder to the project application and setting ‘copy always’. We have attached the working sample for your reference. Kindly try the attached sample on your end and let us know the result.

Hello,

Thank you.

I apologize for my delayed response. I've just reviewed the issue and found a less restrictive solution than including the runtime files in the project. In the "Dockerfile", you just need to add the following lines (before the ENTRYPOINT [...]):


USER root
RUN chmod +x /app/runtimes/linux/native/chrome
RUN chmod +x /app/runtimes/linux/native/chrome_sandbox
RUN chmod +x /app/runtimes/linux/native/chrome-wrapper
USER app


I hope this solution is suitable and doesn't introduce any security concerns or other issues.

Regards.
