I am getting an error when using the IJSReportMVCService.RenderViewToStringAsync() method. My cshtml file is located directly under the Views Folder in my application.
Here is the stacktrace:

I got it to work using 2.7.2. everything is working as expected. Thanks for your help!

Using client version 3.0.1. We are still using .net core 2.2.0

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

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

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);```

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:
