Sorry for the delayed reply. The render command was giving the error as I way trying it during the debugging session, and there was another jsreport process running. Killing the process, will make the command run correctly.

I checked the task manager with the keepAlive parameter and without it. With the parameter, I can see two jsreport processes running, and without it only one. But I will still get the timeout issue.

Yes, still getting a timeout. below is the command and the response

It doesn't seems to be the issue with the environment variables, as I compared all the ones available on the win10 machine, and win 7 vm, and nearly all of them are same. I also tried removing all the ones that are different, but it doesn't changes anything.

I tried checking around jsreport.Local Repo. The issue only happens with the chrome-pdf recipe. test and html recipe work fine.

The error occurs at the following point in jsReport.Local:

An unhandled exception occurred while processing the request.

This is the final list of env variables on the VM:

https://www.dropbox.com/s/neylkhs5qduibxt/env3.txt?dl=0

I also tried after two additional similar variables I found in the initial list, but it didn't helped either:

 worker.StartInfo.EnvironmentVariables.Remove("COMPLUS_ForceENC");
 worker.StartInfo.EnvironmentVariables.Remove("COMPLUS_MDA");

any other pointers to look for?

so, should we expect any fix, like this month, or move to using jsreport.Client with raw jsreport-cli?

No, it seems there is no near future plans to upgrade to windows 10

It seems something with jsreport .net package on windows 7 maybe. I installed windows 7 on vmware on a windows 10 PC, and had the same timeout issue, with the .net core example.

This works, generates the pdf with foo.

C:\Users\xxx\AppData\Local\Temp\jsreport\dotnet\binary-default-2.3.1.0>echo foo > in.html

C:\Users\xxx\AppData\Local\Temp\jsreport\dotnet\binary-default-2.3.1.0>jsreport.exe render --template.content=in.html --template.engine=handlebars --template.recipe=chrome-pdf --out=out.pdf
starting rendering process..
rendering has finished successfully and saved in: C:\Users\xxx\AppData\Local\Temp\jsreport\dotnet\binary-default-2.3.1.0\out.pdf

I found the exe at the path, but What do you mean by: "That one is able to render chrome for you?"

and yes, unfortunately, that is the only windows 7 machine available for me.

no, not even windows defender.

I tired after deleting the folder, but still getting the same error.
