REST API for the Projected Absence Balance

Summary: We have a requirement where other system is expecting Projected Absence Balance via REST API. As per Oracle documentation, we can achieve the same by using below REST API. But when we are trying to pass the details (trying Example) then we are getting 404 Not Found error. Does anyone have this issue?

As per Document:

/hcmRestApi/resources/11.13.18.05/planBalances?finder=findByPersonIdPlanIdLevelDate:personId={personId},planId={planId},balanceAsOfDate={balanceAsOfDate}

Trying Example:
