Exception thrown while displaying Telerik report when deployed in IIS

[Chun]

Hello,

One of our environments that is hosted on a local server is throwing the stack trace below when trying to open up any of our custom reports. We do not have this issue in any of our environments that are hosted on Azure.

The local server has the latest 5.0 version of ASP.NET and the latest 3.1 version of .NET Core installed. Would you have any idea what may be causing this?

exceptionType: "System.ArgumentException"

Hi Chun,

The Stack Trace of the error states that the report definition cannot be resolved. It indicates also that the REST Service utilizes TypeReportSourceResolver that uses internally the TypeReportDocumentResolver for creating an instance of the CS/VB report type.

A possible reason for the failure may be that the assembly with the reports cannot be accessed by the service.

Another reason may be that the assembly with the reports is built with an incompatible framework.

I suggest checking whether the assembly with the reports is deployed with the REST Service and that it is built with a compatible framework.

Regards,
Todor
