Hi @jan_blaha
I was able to resolve this issue by installing few dependencies for Debian. Here is the modified Docker file in case some one else faces similar issue.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
# Below dependencies are required for Debian
RUN apt-get update && \  
         apt-get install -y ca-certificates fonts-liberation libappindicator3-1 libasound2 libatk-bridge2.0-0 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgbm1 libgcc1 libglib2.0-0 libgtk-3-0 libnspr4 libnss3 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 lsb-release wget xdg-utils

RUN apt-get install -y --no-install-recommends libgconf-2-4 gnupg git curl 
libgconf-2-4 && \
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \

sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' && \

apt-get update && \ 

apt-get install -y lsb-release google-chrome-stable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst libxtst6 libxss1 --no-install-recommends && \

rm -rf /var/lib/apt/lists/*

ENV chrome_launchOptions_executablePath google-chrome-stable

ENV chrome_launchOptions_args --no-sandbox,--disable-dev-shm-usage,--single-process,--no-zygote

However this has increased the overall docker image size. Hence wanted to check if all of these dependencies are required or not?

Can you please help with this?
Let me know if I need to share any other information.

@jan_blaha Thanks for your explanation. So i can take stream from report.content and return a byte array or File?
If I am using JsReportMVCService.RenderAsync then i don't need to use the MiddlewareFilter?

@jan_blaha Can you please help with this?

Hi

I am trying to configure JSReport to return PDF from static HTML. I am facing Unhandled exception. This is the same code.

   [MiddlewareFilter(typeof(JsReportPipeline))]
   public async Task<jsreport.Types.Report> InvoiceWithCover()

    {

        var report = await JsReportMVCService.RenderAsync(new RenderRequest()

        {

            Template = new Template

            {

                Content = "<html><body><h1>Hello</h1></body></html>",

                Engine = Engine.None,

                Recipe = Recipe.ChromePdf

            },

            Options = new RenderOptions()

            {

                Preview = true

            }

        }); 
       return report;
 }

This is exception message

How do we go about generating Word reports from Razor Views using JSReport? Any examples around that?

code_blue

Thanks for the explanation

code_blue

Thanks Jan for answering the questions and I am referring to the docs. I have just started to look at JSReport hence trying to figure out things.

I am referring to this the below section
https://jsreport.net/learn/dotnet-local
and had the question why we need to install Chrome inside Docker container if JSReport.Binary already has chrome?

code_blue

When using JSReport AspNetCore inside Docker do we need to install any dependencies for JSReport or a simple RUN dotnet restore should work?
Any examples running in Docker with AspNetCore will be helpful

code_blue

Is there a JSReport Feature roadmap so we know what new features we can expect?

code_blue

Hi Jan

Thanks for your response. One more question, do we need chrome be installed in the server where we are deploying JSReport.
I am using JSReport.Local & JSReport.Binary?

code_blue

Is the AspNetCore JSReport package actively updated? I am trying to use it in an new project and just wanted to check on how frequently it is being worked upon?
Also how does JSReport compare with Puppeteer /PuppeteerSharp
