Telerik Reporting HTML 5 Report Viewer: Error registering client instance

[KV]

Hi, 

I'm having an issue with the HTML 5 report viewer. The initial POST request  to create a client Id fails: 

http://thoitrangkv.localhost.com/api/reports/clients

And it happens for every reports though they used to be working. I have not made changes to the report code, so I suspect the issue may have something to do with my build process. 

Please assist. Thank you

Hello Hao,

I believe we resolved the issue in your support ticket on the same question. For anyone concerned, below you can find a quote from my response in the ticket:

"If you have recently upgraded your project, please double-check if all report definitions, referenced assemblies and the viewer's template files use the same Telerik Reporting version. For more details, check the manual upgrade instructions in the Upgrading Telerik Reporting Projects help article.

Then verify the connection string used in the report are copied in the REST service's project, and they allow you to connect to the database.

Finally, delete the cache, check the permissions for the user to read/write it and restart the application."
