My code is:

var rs = new LocalReporting().UseBinary(JsReportBinary.GetBinary())
                .Configure(cfg => { cfg.TrustUserCode = true; cfg.ReportTimeout = 260000; cfg.Chrome = new ChromeConfiguration { Timeout = 260000 }; return cfg; }).AsWebServer().Create();

 await rs.StartAsync();

.
.
.

 var rpt = await rs.RenderAsync(new RenderRequest()
 {
     Template = template,
     Options  = new RenderOptions { Timeout = 260000 }
 });

I am running all the newest jsreport package versions. What is going on here? Thanks

Are you planning on releasing that today?

Also, I am running .NET Framework 4.8

Hi I am getting this strange error when building jsreport pdfs. I am using all the latest jsreport packages. I am running multiple reports in parallel and I am guessing this is what is causing the issue, but I have always been doing it this way and it has never not worked until right now. Jan I need help!!

<Message>An error has occurred.</Message>

I had to instantiate a TemplatingEngineConfiguration and then set the timeout property but that seems to have done it. Much appreciated Jan!

Hi I am running jsreport in my web application on production (iis 7, .net 4.0 integrated app pool, windows server 2008 R2) and I am getting this error whenever trying to run a report.

 Error rendering report: instance has been daemonized and initialized successfully (pid: 182492)A critical error occurred    while trying to execute the render command: Timeout during evaluation of pdf-utils operations (1).

Here is the code the is not working. If I run each report by themselves without any pdf util ops they come out, but it does not work when I combine them. The chrome timeout is set to 260000 ms but it times out sooner than that. This report runs fine and very quick in the local environment. Any ideas?

var rs = new LocalReporting().UseBinary(JsReportBinary.GetBinary()).Configure(cfg => { cfg.HttpPort = 3000; cfg.Chrome = new ChromeConfiguration { Timeout = 260000 }; return cfg; }).AsUtility().Create();

I am having trouble getting images to show in the headers and footers on my pdf. There is strange behavior though. Here is my code for creating the report:

        var rs = new LocalReporting().UseBinary(JsReportBinary.GetBinary()).AsUtility().Create();
        Template template = new Template()
        {
            Recipe = Recipe.ChromePdf,
            Engine = Engine.None,
            Content = this.RenderViewToString("Overview", GetOverviewModel()),
            Chrome = new Chrome
            {
                Landscape = true,
                Format = "A4",
                MediaType = MediaType.Screen,
                MarginBottom = "80px",
                MarginLeft = "10px",
                MarginRight = "10px",
                MarginTop = "10px",
                Scale ="0.8",
                FooterTemplate = this.RenderViewToString("_FooterPartial", new { }),
                HeaderTemplate = "",
                DisplayHeaderFooter = true,
                PrintBackground = true
            }
       };
      var rpt = await rs.RenderAsync(new RenderRequest()
        {
            Template = template
        });

Here is the footer partial page. I am using the entire path to link the image. When I navigate to the link directly the image shows fine.

  @using mmars.Models
  <table style="margin-left:85%">
       <tr>
            <td class="text-center">
                <p style="font-size:11px; margin:0px">Powered by:<br /></p>
            </td>
            <td class="text-center">
                <img src="http://localhost:1411/Graphics/MMcube.png" style="width:40px;height:40px;" />
            </td>
     </tr>
  </table>

The strange behavior is that the footer on the first page does not even recognize the image, and then on subsequent pages, sees that there is an img but it cannot load it:

footer_img_1

footer_img_2

Any ideas on what might be causing this? Even when I put the html directly into the FooterTemplate string instead of calling RenderViewToString, I get the same behavior.

Hi I am a bit confused on how I can combine the pdfs created from 2 separate razor views. One thing I was trying was to save the report content to a byte[] and then return that for both views and go from there to merge the pdfs but the byte[] is always empty:

 [EnableJsReport()]
 public byte[] /*ActionResult*/ Overview()
 {
    MemoryStream buffer = new MemoryStream();
    HttpContext.JsReportFeature().Recipe(Recipe.ChromePdf)
            .Configure((r) => { r.Template.Chrome = new Chrome { 
                       Landscape = true, 
                       Format = "A4", 
                       MediaType = MediaType.Screen, 
                       MarginBottom = "50px", 
                       MarginLeft = "0px", 
                       MarginRight = "50px", 
                       MarginTop = "50px" }; })
            .OnAfterRender((r) =>
            {
                r.Content.CopyTo(buffer);
                //r.Content.Seek(0, SeekOrigin.Begin);
            });
    return buffer.ToArray();
}

The other option I was trying was to create a template which I found from another forum post, but I am not sure how to get the razor view content into the string content for the template:

        var rs = new LocalReporting().UseBinary(JsReportBinary.GetBinary()).AsUtility().Create();

        var report = await rs.RenderAsync(new RenderRequest()
        {
            Template = new Template()
            {
                Recipe = Recipe.ChromePdf,
                Engine = Engine.None,
                Content = "" //how to get razor view here?
            }
        });
        var memoryStream = new MemoryStream();
        await report.Content.CopyToAsync(memoryStream);
        memoryStream.Seek(0, SeekOrigin.Begin);
