To extend time out during js report generation in asp.net core

I have a rather complicated html code in the view and the report needs a longer time than the default 30 seconds to generate the structure. I'm using JSReport version 2.7.1. Initially, I tried modifying the jsreport.config.json file from "chrome": { "timeout": 180000 } to a very big number but that did not work.

And so ,I have been trying to extend jsreport timeout and here is where I am at.

 HttpContext.JsReportFeature()
            .Recipe(Recipe.ChromePdf)
            .Configure((r) => r.Template.Chrome = new Chrome
            {
                Landscape = true,
                Format = "Legal",
                HeaderTemplate = header,
                FooterTemplate = footer,
                DisplayHeaderFooter = true,
                MarginTop = "95px",
                MarginLeft = "20px",
                MarginRight = "20px",
                MarginBottom = "40px"
            }
            )
            .Configure((r) => r.Options = new jsreport.Types.RenderOptions
             {
                 Timeout = 600000
             });

In the above case the styling works but the timeout is not implemented. However if i reverse the order of the configure and put the timeout first and the styling next, the timeout works but not the styling.

I have also tried the below method and even here it's either a case of report loading without the style or timing out with the error "JsReportBinaryException: Error rendering report: starting rendering process..rendering has finished with errors:A critical error occurred while trying to execute the render command (2). Timeout Error: pdf generation not completed after 30000ms (1). caused by error (2):-> stackError: at onCriticalError (D:\snapshot\jsreport\node_modules\jsreport-cli\lib\commands\render.js:302:19) at D:\snapshot\jsreport\node_modules\jsreport-cli\lib\commands\render.js:298:12caused by error (1):-> meta = {"workerTimeout":true,"logged":true}-> stackError: at Timeout.

 HttpContext.JsReportFeature()
 .Recipe(Recipe.ChromePdf)
 .Configure(cfg =>
 {
     cfg.Options = new RenderOptions
     {
         Timeout = 600000
      };
      cfg.Template.Chrome = new Chrome
      {
                     Landscape = true,
                     Format = "Legal",
                     HeaderTemplate = header,
                     FooterTemplate = footer,
                     DisplayHeaderFooter = true,
                     MarginTop = "95px",
                     MarginLeft = "20px",
                     MarginRight = "20px",
                     MarginBottom = "40px",
                     PrintBackground = true
      };                     
      })

Is there a way I can combine both and have both working?

as you said your html is rather complicated you can set templatingEngines.timeout and extensions.scripts.timeout in jsreport.config.json
