Problem with PhotonView.RPC

hi, i am new to unity and photon networking and i am converting my Maltiplayer game made using ultimate unity networking into Photon networking. with the tutorial(came with sdk) i have converted my all unity networking code to photon networking using photon converter. i have fixed all the bugs but at runtime i have having problem with PhotonView.RPC method. it is giving me this error.

"PhotonView with ID 1000 has no method "SetCurrentCharacter" that takes 0 argument(s):" and my code is as follows.

 void SetupAvatar(int characterId)
     {
         if (character != null)
             PhotonNetwork.Destroy(character);
         character = (GameObject)PhotonNetwork.Instantiate(characterPrefabs[characterId], Vector3.zero, Quaternion.identity, 0);
         
         // Sync Avatar configuration
         if (PhotonNetwork.isNonMasterClientInGame || PhotonNetwork.isMasterClient) {
             Debug.Log("Before Set Current character!!!");
             photonView.RPC("SetCurrentCharacter", PhotonTargets.AllBuffered);
         }
     }
 
     [RPC]
     void SetCurrentCharacter(PhotonViewID characterViewId)
     {
         Debug.Log("Set Current Character Method!!!");
         PhotonView view = PhotonView.Find(characterViewId.ID);
         
         if (view == null)
         {
             PhotonNetwork.Destroy(gameObject);
             return;
         }
         
         character = view.gameObject;
         character.transform.parent = transform;
         character.transform.localPosition = Vector3.zero;
         character.transform.localRotation = Quaternion.identity;
         
         _animation = character.animation;
         if (_animation != null)
             enabled = true;
     }

i do not know how to get the photon View id so i can pass it as a parameter in this method.

any help will be greatly appreciative. thanks.
