Thank you.

Hello @jan_blaha ,
Thank you for quick response.

Yes we use windows service to keep jsreport running.
Yes, we are using license key for jsreport .(Does it cause any such kind of issues , if we use license and without license version ?).

We will monitor if we face same issue in future and update you.

Appreciate your support

Hello team, @jan_blaha ,
Good morning ,we are using jsreport single file executable (for jsreport server) and rendering report from .Net core web application. It works fine with latest .exe available on githut(https://github.com/jsreport/jsreport/releases).
But once new release available for .exe, our application will stop working and we have to download and install new exe on server and it works again.
This is very unstable and impacting work.
Please can you suggest is there any way to get stable version of .exe which works all the time.
It will be great if you suggest any other best option for using jsreport server for windows .

Below are few application details:
.Net version -.Net core 6, .Net framework 4.8
Hosting - On windows server
jsreport server- installed single executable on window server
Output- Report render in pdf format

sample code from web application:

ReportingService rs = new ReportingService("http://localhost:5488");

var customReport = rs.RenderAsync(CustomRenderRequest).Result;
customReport.Content.CopyTo(File.OpenWrite("customReport1.pdf"));

private static RenderRequest CustomRenderRequest = new RenderRequest()
{
Template = new Template()
{
Content = File.ReadAllText("Pathofhtmlfile.html"),
Engine = Engine.Handlebars,
Recipe = Recipe.ChromePdf
},
Data = new
{
message = " Testing jsreport for .NET!!!"
}
};

Error details:
Below error occurs after a month or so (specially when there is new .exe available), once we install new exe it works fine again.

Please share your suggestion on this issue to make it stable for all time.

Thank you !!
