TSR Integration->Add Employee->Error on null postal code value

When postal code is not given for addEmployeeTour there is an error.

Eg.
{
"Company":"13480",
"JobID":"J0053",
"JobPosition":"Dev Lead",
"CandidateID":"C0298",
"FirstName":"Test",
"LastName":"EmpTwentyeightone",
"EmailID":"ssablaka29@hg.com",
"EmploymentStartDate":"04/05/2017",
"AnnualSalary":"$130000"
}

Excepted Behaviour-There is no error,employee gets added successfully.

Also tour id is required field.So change error message.
