Html to PDF generation -Blazor Server app - Apple M4 - Syncfusion.Pdf.PdfException - Blink files are missing

[SathyaR]

Hi,

Environment: Apple m4 macair, .Net 9.0, Rider IDE, Syncfusion Blazor components v29.1.41

I am getting the following exception when attempting to run code that converts html to PDF using Syncfusion libs.

Syncfusion.Pdf.PdfException: Blink files are missing at /Users/sathyar/Webdev/HmsBlazorServer.App/bin/Debug/net9.0/runtimes/osx/native

My code is as follows -

//Initialize HTML to PDF converter with Blink rendering engine
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter(HtmlRenderingEngine.Blink);
BlinkConverterSettings blinkConverterSettings = new BlinkConverterSettings();

//Set command line arguments to run without the sandbox. 
blinkConverterSettings.CommandLineArguments.Add("--no-sandbox");
blinkConverterSettings.CommandLineArguments.Add("--disable-setuid-sandbox");

//Set Blink viewport size.
blinkConverterSettings.ViewPortSize = new Syncfusion.Drawing.Size(1000, 0);
//Assign Blink converter settings to HTML converter.
htmlConverter.ConverterSettings = blinkConverterSettings;

//Convert HTML string to PDF
PdfDocument document = htmlConverter.Convert(pageContent, Path.GetFullPath("Services/InvoiceService"));

I have the same code working fine when running from Windows 11 and on Linux.

I have included the following packages in my project -

   Syncfusion.HtmlToPdfConverter.Net.Mac

   Syncfusion.HtmlToPdfConverter.Net.Windows

   Syncfusion.HtmlToPdfConverter.Net.Linux

On the support site, it is suggested to copy the contents of the Chromium.app folder to the folder specified in the exception. i.e -

/Users/sathyar/Webdev/HmsBlazorServer.App/bin/Debug/net9.0/runtimes/osx/native

But I am seeing only the following folders on my machine -

 -   /Users/sathyar/Webdev/HmsBlazorServer.App/bin/Debug/net9.0/runtimes/osx-arm64/native

 -   /Users/sathyar/Webdev/HmsBlazorServer.App/bin/Debug/net9.0/runtimes/osx-x64/native

I created a symlink for a folder osx pointing to the osx-arm64 and copied over the contents of the Chromium.app file - but I am still seeing same error.

The contents of the Chromium.app looks as below - 

 ----------   

sathyar@sathyasmba Contents % ls -l

total 32

drwxrwxr-x@ 3 sathyar staff 96 29 Dec 23:00 Frameworks

-rw-rw-r--@ 1 sathyar staff 10906 29 Dec 22:46 Info.plist

drwxrwxr-x@ 3 sathyar staff 96 29 Dec 23:00 MacOS

-rw-rw-r--@ 1 sathyar staff 8 29 Dec 22:46 PkgInfo

drwxrwxr-x@ 88 sathyar staff 2816 29 Dec 23:00 Resources

----------

 Any pointers to solve this issue ?

Thanks

Hi, I upgraded the Syncfusion components to 29.2.4 and now I see the following folder created 

  /Users/sathyar/Webdev/HmsBlazorServer.App/bin/Debug/net9.0/runtimes/osx/native

with Chromium.zip file within it. On extracting the Chromium.app's contents into this folder, I am able to generate pdf from html.

This issue may be considered closed. Thanks
