Environment

Product	Reporting

Error Messages

JSON

{
    "message": "An error has occurred.",
    "exceptionMessage": "Method 'get_ProductClaims' in type 'RuntimeInvalidLicenseStatus' from assembly 'Telerik.Reporting, Version=20.0.26.211, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' does not have an implementation.",
    "exceptionType": "TypeLoadException",
    "stackTrace": null
}

Cause

The error occurs because Telerik Reporting version 20.0.26.211 is incompatible with the Telerik.Licensing NuGet package version 1.7.0.

A newer version of Telerik Reporting is required for compatibility.

Solution

To resolve the issue, update the Reporting packages/assemblies in the project to Progress® Telerik® Reporting 2026 Q1 (20.0.26.304), which is compatible with Telerik.Licensing version 1.7.0. Ensure that all relevant dependencies are updated to avoid compatibility issues.

If you do not wish to update the Reporting dependencies right now, revert to using version 1.6.40 of the Telerik.Licensing NuGet package.
