Error registering Reports Controller routes

[Chris]

I am receiving a System.NotSupportedException of "Adding or removing items from a 'HttpRouteCollection' is not supported. Please use a key when adding and removing items." when my application hits the ReportsControllerConfiguration.RegisterRoutes() method. 

Thank you for assistance in advance.

Hello Chris,
Please check if you have all settings from the How To: Add Telerik Reporting REST Web API to Web Application help article. The routes we register for the Reporting REST WebAPI service are listed in the How to change the registered by default Telerik Reporting REST Web API routes KB article.


If you need further help, please elaborate on your project's settings and routes configuration.

Regards,

The real fix for this issue is to make sure that you have installed the WebAPI 2.2 Nuget package into the project. Build. All should be OK.

I am receiving the same error. I have verified all the settings according to the How To article. I have also verified the WebAPI 2.2 Nuget package is installed. I am using the 5.2.3 version of the package. I also added the following to the web config as instructed when using a higher version than specified in the article.

<dependentAssembly>
        <assemblyIdentity name="System.Web.Http" culture="neutral" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.2.3"/>
      </dependentAssembly>

        <bindingRedirect oldVersion="0.0.0.0-65535.65535.65535.65535" newVersion="5.2.3"/>
      </dependentAssembly>​

 Any help is greatly appreciated.

 

Thanks

Hello Carli,

Please check if the Reporting REST service is configured correctly and responds on call for formats in browser -  How To: Add Telerik Reporting REST Web API to Web Application, and verify there are no duplicating routes registered in the Global.asax.

If the issue still occurs, please check the status and responses of requests via Fiddler, and open a support ticket with a demo project illustrating the problem and the details from Fiddler.
