Problems With User Password Reset


I am trying to reset the user password by sending the following POST from Kibana UI Developer Console but I keep running into this error

Here is my POST

POST _security/user/username/_password 
"password": "newpasswordtoupdate"

Here is the ERROR

  "error": "no handler found for uri [/_security/user/username/_password?pretty] and method [POST]"

The URI path is the same that elasticsearch has in its official documentation

Is there a different URI path for Password reset for Opendistro because the error shows a different handler could be the problem here?
