unable to declare custom context variable via Designer.


Im trying to declare a custom context variable in mediator, so that I can get the value of a certain paraeter in the incoming GET request and route the request to different endpoints based on the parameter value.

I end up running into null pointer exception irrespective of following all the pre-requisites advised in the Centrasite documentation.

im running 9.5 SP1. Any help would be appreciated to get this logic working.

Thanks and Regards
