Unable to index the values when datatype of variable is recordtype

Hello Everyone,

I would like to apply filter for the process report using queryprocessanalytics.Configured the queryfilters as below but none of the approach helped me.The result is null. 

1.

a!queryFilter(
field: index(index("c7","employeeDetails",{}),"employeeId",{}),
operator: "=",
value: "7"
),

2.

a!queryFilter(
field: "c7[recordTye!EmployeeDetails.fields.employeeId]"
operator: "=",
value: "7"
),

I have tried to index the same way on the process report data fields > Definition but not able to get the indexed value.

Is there any way to filter the values of particular field in record type.
