If you unselect all the days from the Day of the Week in the recurrence rule of a scheduled task of data alert, the task can be saved but will throw an Internal Server Error and you won't be able to list the available tasks on the server.
The linked muted video demonstrates the problem.
Here is the error stack trace produced by the ServiceAgent:
Telerik.ReportServer.ServiceAgent.exe Information: 0 : Loaded 37 tasks in total. Telerik.ReportServer.ServiceAgent.exe Error: 0 : System.IndexOutOfRangeException: Index was outside the bounds of the array. at Telerik.WinControls.UI.Scheduler.ICalendar.CalHelper.TryParseRecurrenceRuleProperties(RecurrenceRule result, IEnumerable`1 keywordPairs) at Telerik.WinControls.UI.Scheduler.ICalendar.CalHelper.TryParseRRuleCore(String valueToParse, RecurrenceRule& result) at Telerik.ReportServer.Web.Utils.Appointment..ctor(DateTime startUtc, String recurrenceRule) at Telerik.ReportServer.ServiceAgent.Tasks.TaskInfo.UpdateNextOccurrenceTime(DateTime utcFrom, DateTime utcTo) at Telerik.ReportServer.ServiceAgent.Services.SchedulingService.CalculatePendingTasks(List`1 pendingTasks) at Telerik.ReportServer.ServiceAgent.Services.SchedulingService.MainLoop() at Telerik.ReportServer.ServiceAgent.Services.SchedulingService.StartMain()
We cannot delete reports using the Report Server UI. After you select the report and choose to delete it, the report appears as removed from the list, even though the details are still visible. If you refresh the page, the report is still there.
Further investigation revealed that the ServiceAgent is not running. There is no proper error message indicating this though.
The issue is reproducible only with the Report Server running under HTTPS. When under HTTP there is a proper message stating that the ServiceAgent is stopped.
I was on a remote web session with an engineer and we discovered that the Scheduler UI isn't saving the changed password to the database.
The environment that I use is below.
The steps to reproduce are as follows.
During the Remote Web Assistance Session, we tried a Gmail SMTP server and received the same results.
We also enabled tracing and noticed an error in the event logs which I will attach here.
Please let me know if you need any additional information.
In a Scheduled Task created with the Report Server API, the day of the week in the recurrence rule is not shown in the Edit Task window of the Report Server Manager. A detailed description of the issue is available in this forum post.
I create a Report Book in the Standalone designer that is connected to my Report Server. When I add the first two reports, the Report Book is rendered as expected. When I add the third one, it fails with the exception:
Report processing was cancelled. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Here is a link to a short video demonstrating the problem. All the individual reports run correctly.
I have a report that is scheduled to happen first day of every month. The thing is that when I look at the next occurrence of the report, it is happening on the second day of the month. I am attaching the report settings herewith. Please let me know if you have a solution/ explanation to get this corrected. Thanks a lot in advance.
Getting this error in the browser when trying to preview a report:
Error registering the viewer with the service. An error has occurred. Incorrect value (null) deserialized. Make sure you are using CacheStorage inside single-instance application deployment only.
A possible reason is the cache for the Report Server used for previewing reports has become corrupted. A workaround is explained in the Telerik.Reporting.Cache.CacheStorage.AddInSet NullReferenceException KB article.
It will be very convenient for the user to be able to clear the cache directly from the Report Server Manager UI.
It seems that when you try to open two tabs in the same browser looking at different websites, the browser gets confused about the URL that is sending the request. Issue is related to CORS protocol and HTTP caches.
It sounds like something needs to be changed on the report server so that even if it gets cached it would still allow access when I switch sub domains. Or something on the viewer side to clear the cache.
