.NET6 Telerik Reporting not working when deployed in IIS.

Report is working fine in local IIS but not in IIS server. See error details below.

Error creating report instance (Report = 'AttendanceTagging.trdp').
An error has occurred.
A possible object cycle was detected. This can either be due to a cycle or if the object depth is larger than the maximum allowed depth of 64. Consider using ReferenceHandler.Preserve on JsonSerializerOptions to support cycles. Path: $.

Hello Ronald,

I noticed that you have posted about the same issue in the "Error creating report instance" when starting viewer in .NET7 RC1 application ( item and I have answered the question there.

The safest option for resolving the problem is to use the latest version of Telerik Reporting - Telerik Reporting - ProgressĀ® TelerikĀ® Reporting R1 2023 SP1 (

Please let me know if you have any additional questions.
