We used WebKit Rendering Engine to convert HTML to PDF - https://www.syncfusion.com/blogs/post/HTML-to-PDF-Conversion-by-using-the-WebKit-Rendering-Engine.aspx
and got blank sample.pdf in your sample. We had correct temp
\4b544231-fd9b-4788-845c-5b29991da0e0.pdf in result.WebKitFilePath (e.g.
but sample.pdf appeared empty.
We double checked that we have no any of this cases:
If the webpage (HTML) is not available or accessible.
If msvcp.dll and msvcr.dll are not present in the SysWOW64 location.
If any QT binary is not present in the mentioned location.
Can you please explain why do we have blank document in result?
