I keep getting this error not always though.
The report however is still responsive to events BUT each event adds a row to the error with the same message. I have no clue what this error and not much info on google also.
The only resolution i have found is to refresh the web page. This error never comes up in the Desktop authoring. It only comes up on the Web page.
Im using Chrome Version 50.0.2661.102 m.
Hi Arpan, messages like this ("unexpected error") mean that there's a problem on the Tableau Server side. The best approach is to contact support. If you're not running the latest maintenance release, you might want to install to see if that solves the problem.
