Null Pointer Exception and cast error when scheduling a report using REST_V2 jobs api

Problem Description:

Normally, you would create an input control for every parameter so that you can refer to the parameter when running REST_V2 jobs PUT calls.

On v6.4.2, you were able to run the PUT call without input control defined for each parameter.  However, on v7.9.1, you are getting a null pointer exception and a type cast error.  See attached example PUT bodies.
