As in the code example I'm using "Recipe = Recipe.ChromePdf" and no staticPDF recipe. And locally on my windows machine the rendering with the azure function in .net is working fine. If I switch there to "staticPDF" then I get the same error as on the linux machine on the azure cloud. So it seams there the chromepdf is somehow ignored or a fallback goes to staticPDF?

Another question: I tried running the node.js example on a static azure plan (OS: linux, Plan: (B1: 1)) and I get the following error:

Error: Failed to launch chrome!
[0330/091143.853361:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

On a consumption Azure plan, as it is mentioned in the example, this is working. Has someone any idea?

I wanted to achieve the exakte behavior as in the node.js example but in a .net core environment with the jsreport binaries, local client and azure function. So you have also no experience or example with such a setup? Because when I start the azure function locally on my windows machine it is working.
Is there any possibility in the node.js example to point to the /data file stored in a blob storage? If yes can you give me a short example?

I'm want to run jsreporting with local reporting in an azure function for scalability.

My function code is:

			[FunctionName("PDFCreator")]
			public async Task<IActionResult> Run([HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req, ExecutionContext context)
			{
				Report report = null;
				try
				{
					var reportingService = new LocalReporting()
					.UseBinary(RuntimeInformation.IsOSPlatform(OSPlatform.Windows)  ?
	        				jsreport.Binary.JsReportBinary.GetBinary() :
	        				jsreport.Binary.Linux.JsReportBinary.GetBinary())
					.KillRunningJsReportProcesses()
					.AsUtility()
					.Create();

					var report = await reportingService.RenderAsync(new RenderRequest()
					{
						Template = new Template()
						{
							Content = "<span>hello {{:Message}}</span>",
							Engine = Engine.Handlebars,
							Recipe = Recipe.ChromePdf
						},
						Data = new { Message = "world" }
					});

					report.Content.Position = 0;   //resets stream
					var fileStream = new FileStreamResult(report.Content, "application/pdf");

					return fileStream;
				}
				catch (Exception ex)
				{
					
				}
			}

used jsreport packages:

• jsreport.binary.linux 2.11
• jsreport.binary 2.11 (for locally windows machine)
• jsreport.local 2.3.1

If I start the azure function locally on a windows machine it is working fine.

Now I deployed the function into an azure function app on a linux machine.

• Operatin system: linux
• Plan B1:1 mode basic

But I get an error: Rendering does not finish and gets an error after 4 min.

Am I doing something wrong with my setup?

Thanks
