3. Cant convert Razor View to PDF while running jsreport inside a docker container.

Cant convert Razor View to PDF while running jsreport inside a docker container.

  • P

    I have a docker container set up with jsreport running. Here is the content of my docker file FROM jsreport/jsreport:2.5.0

    In my controller I have decorated the action with
    [MiddlewareFilter(typeof(JsReportPipeline))] attribute and added

    this.HttpContext.JsReportFeature().DebugLogsToResponse().Recipe(Recipe.ChromePdf).OnAfterRender((r) => HttpContext.Response.Headers["Content-Disposition"] = $"attachment; filename=\"{this.Form}.pdf\""); before returning the view.

    This is not working for me. I have copied the logs from my docker container:

  • You use FROM jsreport/jsreport:2.5.0 but in logs I see Using extension pdf-utils@1.6.1.
    This pdf utils version isn't part of jsreport@2.5.0. Have you done some customizations in your dockerfile?

    The trouble is this line. It looks the recipe definition isn't properly passed to the jsreport endpoint. Not sure why at this moment.

     Rendering anonymous template { recipe: undefined, engine: undefined }

    How do you add jsreport to the asp.net web app? Something like this?

    services.AddJsReport(new ReportingService("http://localhost:5488"));

    Do you have some extra code in the controller action, maybe there is some problem.

    No my dockerfile is just one line which pulls the jsreport image. I do not pass a config file or anything. The contents of the dockerfile are FROM jsreport/jsreport:2.5.0. Is there a later version i could try?

    And yes, i add jsreport to my webapp exactly like that services.AddJsReport(new ReportingService("http://localhost:5488"));

    My controller code:

         response.VehicleName = "Test";

     this.HttpContext.JsReportFeature().DebugLogsToResponse().Recipe(Recipe.ChromePdf).OnAfterRender((r) => HttpContext.Response.Headers["Content-Disposition"] = $"attachment; filename=\"{this.Form}.pdf\"");

      return this.View("MyView", response);```

    That is strange. That image for sure has different pdf utils version.

    Is there a later version i could try?

    2.7.2 is the current latest
    https://hub.docker.com/r/jsreport/jsreport/tags
    https://github.com/jsreport/jsreport/releases

    Do you have the latest jsreport.AsppNetCore nugget package? it should be 2.0.2.
    https://www.nuget.org/packages/jsreport.AspNetCore/

    Sorry, one thing i just noticed is that my Dockerfile was FROM jsreport/jsreport:latest. Maybe that is the problem. I have specified it to be FROM jsreport/jsreport:2.7.2 now. I will run it again and try and let you know.

    Yes, using the latest NuGet Package, which is 2.0.2

    Using version 2.7.2 still shows using pdf utils version. Here is the log

  • Yes, this is ok. No problem with the 2.7.2. and the log.

    What is your jsreport.Client version?. I have 3.0.1. What is your .net core version?
    0_1586801587917_upload-729e32d3-e88a-40e6-a959-9e2eee09674d

    Do you get the same if you start from scratch? Create the default asp.net core web app, add jsreport.AspNetCore and jsreport.Client nugets and try it out?
