Third Party PUN RPC call error

current I am facing some error with PUN

Code (CSharp):

1. photonView.RPC(
2.             nameof(SendPlayerInfo), RpcTarget.All,
3.             (object)(new int[] {
4.                 curProfile,
5.                 curAvata,
6.                 currentPlayer.id
7.             })
8.         );
9.  
10. void SendPlayerInfo(int[] obj){
11. ....
12. }

above my code don't work well now.
follow is my errors. how can I solve this issue ?
RPC method 'TurnToCurrentDirection(Int32[])' not found on object with PhotonView 3. Implement as non-static. Apply [PunRPC]. Components on children are not found. Return type must be void or IEnumerator (if you enable RunRpcCoroutines). RPCs are a one-way message.

You need to apply the attribute [PunRPC] to the method SendPlayerInfo.

 

thank you for your kind reply. I've already solved that problem. my code have that attribute at that time.
problem was in other part of code.
