GetGameList failed: OperationResponse 217: ReturnCode: -2 (Unknown operation code). Parameters: {}

hello Photon server use "photon-server-sdk_v4-0-29-11263.exe" . Then "Photon Unity Networking" connect my server .

TypedLobby sqlLobby = new TypedLobby("myLobby", LobbyType.SqlLobby);    // same as above
string sqlLobbyFilter = "C0 = 0";   // request games with mode 0
PhotonNetwork.GetCustomRoomList(sqlLobby, sqlLobbyFilter);

received error "GetGameList failed: OperationResponse 217: ReturnCode: -2 (Unknown operation code). Parameters: {}" Is this operation not implemented on the server side or my server outdated version?
