TaskCanceledException：呈现jsreport时取消了任务

Question

I'm trying to render a jsreport that contains too much data and when it takes too long to render shows me this message:

TaskCanceledException: a task was cancelled.

If I load less data the report works well.

My question is, there is a way to avoid TaskCanceledException and let the rendering time take what it has to take to render the report?

Answer 1

Thanks Ankit Vijay for your response, the answer has to be with the time out as you mention, my solution was the next one

I was using the jsreport embbedserver and i set the time out like this

embeddedReportingServer.ReportingService.HttpClientTimeout = TimeSpan.FromMinutes(40);

With this line of code i stop recieving this error: TaskCanceledException: a task was cancelled while rendering jsreport

Then when i was testing again i got this error with the phanton process:

Unable to render template. Error during rendering report: Timeout when executing in phantom.

At the end i solved it by adding configuration to my embbed server like this

Helper.embeddedReportingServer.Configuration = new
            {

                phantom = new
                {
                    timeout = 900000,
                    numberOfWorkers = 2
                },


                tasks = new
                {
                    numberOfWorkers = 2,
                    timeout = 900000,


                }

            };

The TaskCanceledException most likely should be coming due to timeout.

Try increase timeout through jsreport configuration. You can read more about jsreport configuration here . I have not tried it myself but it should be tasks.timeout property.
