  We aren't planning to release today. Probably Monday.

  However, I am afraid Boris was a bit misleading. He fixed the error handling, not the actual error which will need more investigation.
  Not sure at this moment, maybe it is a race condition on our side and maybe the process is just failing because of not enough resources.
  In that case, you should limit the parallelization on your side.

  In case the problem is persistent and you need to recover please use KillRunningJsReportProcesses and restart.

  var rs = new LocalReporting() .UseBinary(JsReportBinary.GetBinary()) .KillRunningJsReportProcesses()

  I also recommend trying using the "AsWebServer" strategy.
  So far it looks like we have never-ending problems with "AsUtility" and maybe the "AsWebServer" will work better for you.

  OK then, I've just updated my web app. So far so good. That warning disappeared, and the build time is acceptable now.
  Thank you so much for your cooperation!

  Can i modify Template/Data using javascript functions in .Net?

  I don't get it...

  Why don't you just prepare the data you need in the c#?
  The custom jsreport script doesn't make so much sense when you send the whole request specification in the c#.
  It is mostly used when you have a template stored inside jsreport store and want to do some calculation on the incoming data.

  Means I need to call the report template generated from jsreport studio... right..?

  No.

  Right now you use jsreport.Local and jsreport.Binary nugets. These embeds jsreport binary inside and start it from inside your application running inside iis. This can be problematic. I proposed you start jsreport outside iis as a normal process and connect to it from your app. It should be just one line change for you as I demonstrated.
  Here is how you can start jsreport

  Please share somewhere a sample project replicating the problem so we can take a look.
  Or you can try to debug this.

  How can i use pdf utils helper functions in Header and Footer?

  The pdf utils shouldn't be combined with native headers/footer provided through recipe HeaderTemplate/FooterTemplate.

  Here is the .net example
  https://jsreport.net/learn/dotnet-client#pdf-utils

  However, I recommend testing the code/template the first on your local jsreport instance, outside .net.
  Then you can replicate the API call using postman or some tool like that and then try the same with .net.
  You get a better troubleshooting flow with this approach.

  This project (jsreport) has nothing to do with jasper reports.
  The link you provided (jsreports) is from a completely different project, which is actually not being developed for some time as far as I know.

  This signals the chrome missing dependency that should get installed with that:

  RUN apt-get update && \ apt-get install -y gnupg libgconf-2-4 wget && \ 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 google-chrome-unstable --no-install-recommends ENV chrome:launchOptions:args --no-sandbox

  It seems you have twice FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base in your dockerfile.
  It should be there just once. Maybe the apt-get part isn't running actually. Please remove the second FROM declaration and try it again.

  It's possible using pdf utils and merge operation

  Here is a short .net sample if you don't have your templates stored inside jsreport

  Gia,

  You need to make sure the extension is properly loaded into the solution. You do this by installing the extension with npm inside of the jsreport folder. And also make sure that your jsreport.config.json file has the key/value for "discover": true
