Benefits Open Enrollment not processed due to FF Error (FF-1605015)

Summary:

The error is getting triggered randomly and not for all employees. It is getting triggered during Open Enrollment Process (or using Add Open Enrollment). The Fast Formula is trying to check if the employee have kids in HCM as dependents and they are below 26 yrs of age. The child's date of birth is properly entered, still getting error as below:

Formula RGI_CHILD_PRESENT_AGE, line 29, array data value missing. There is no data for array PER_EXT_CONT_DATE_OF_BIRTH, index 5. For example, if an array is set up with only two data values at indexes 1 and 3, such as a[1] = -1 a[3] = -3, referencing an index value other than 1 or 3, such as b = a[2], will raise this error. Correct the formula to ensure that array data exists when referenced.
