Intermittent issue when generate Telerik report

[sg]

Hi,

As per screenshot I attach, on the screen, users have to do some filtering then click on Generate button to show the report.

However, there is an intermittent issue when user generate report, which is "Document/refresh with ID 'xxx' not found". Users have to refresh the screen or click on Generate button again.

Please advise how can we resolve the issue.

Thank you.

Hello,

I am sorry to hear that you are experiencing issues with our product.

I suspect that the document with the corresponding ID cannot be found on the Get Document Info request. This is the request that is performed regularly (each 0.5s). It indicates whether the report is already rendered in the service. However, the problem may occur also in any of the subsequent requests.

For a solution to this problem, please consider upgrading to the R2 SP1 2021(15.1.21.616) version in which we introduced the keep the client session alive functionality which prevents the expiration of the client by continually sending a request to the server, determined by the Reporting REST service's ClientSessionTimeout. Alternatively, you could try increasing the value of the ClientSessionTimeout property. More information on this property and the reporting service can be found in the HTML5 Report Viewer and Reporting REST services article.

In case you need further help, I would like you to do the following:

• Install the Fiddler Jam extension then generate a log and share it with us so that we can see information regarding the requests being sent to the service, console errors, etc.
• Generate a trace listener from the reporting service log and send it to us - How to: Create and Initialize Trace Listeners
• If the reporting service is using .NET Core, see the Troubleshooting reporting implementation into ASP.NET Core application article.

Thank you for using Telerik Reporting!

Hi,

We have tried to increase the ClientSessionTimeout, the issue still persists.

Thus, we  upgraded telerik report to R2 SP2 2021 (15.1.21.616). However, there is another error when it calls /api/reports/formats. Please help.

"ExceptionMessage": "Multiple actions were found that match the request:  Formats on type WebApi.Controllers.ReportsController GetClientsSessionTimeoutSeconds on type WebApi.Controllers.ReportsController", "ExceptionType": "System.InvalidOperationException",
"StackTrace": "   at System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__15.MoveNext()"
