PLS-00306: wrong number or types of arguments in call to 'UPDATE_COMPETENCE_ELEMENT' ORA-06550 State

 I am trying to end date job competences by calling the HR_COMPETENCE_ELEMENT_API.UPDATE_COMPETENCE_ELEMENT API, but it seems to be returning an error "PLS-00306: wrong number or types of arguments in call to 'UPDATE_COMPETENCE_ELEMENT'".I have checked all the possible parameters to be called in the api and i have supplied values for the necessary ones and left the others null.

here is a sample script.

DECLARE

   lc_errmsg                 VARCHAR2 (4000);

   l_object_version_number   NUMBER;

   CURSOR CURSOR1

   IS

      SELECT   *

        FROM   per_competence_elements pce

       WHERE   TYPE = 'REQUIREMENT' AND pce.JOB_ID = 53854;

BEGIN

   FOR i IN CURSOR1
