Third Party Photon OperationResponse 254: ReturnCode: -2

Unity 2018.2.0f2
Photon 1.91

Code that worked until I upgraded from 2018.1 to 2018.2:

Code (CSharp):

1.  
2. Operation failed: OperationResponse 254: ReturnCode: -2 (Unknown operation code). Parameters: {} Server: MasterServer
3. UnityEngine.Debug:LogError(Object)
4. NetworkingPeer:OnOperationResponse(OperationResponse) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:1623)
5. ExitGames.Client.Photon.PeerBase:DeserializeMessageAndCallback(Byte[])
6. ExitGames.Client.Photon.EnetPeer:DispatchIncomingCommands()
7. ExitGames.Client.Photon.PhotonPeer:DispatchIncomingCommands()
8. PhotonHandler:Update() (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/PhotonHandler.cs:158)
9.  

Code (CSharp):

1. Failed parsing address:
2. UnityEngine.Debug:LogError(Object)
3. NetworkingPeer:DebugReturn(DebugLevel, String) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:1574)
4. ExitGames.Client.Photon.IPhotonSocket:Connect()
5. ExitGames.Client.Photon.SocketUdp:Connect()
6. ExitGames.Client.Photon.EnetPeer:Connect(String, String, Object)
7. ExitGames.Client.Photon.PhotonPeer:Connect(String, String, Object)
8. NetworkingPeer:Connect(String, ServerConnection) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:590)
9. NetworkingPeer:OnStatusChanged(StatusCode) (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/NetworkingPeer.cs:2175)
10. ExitGames.Client.Photon.<>c__DisplayClass146_0:<EnqueueStatusCallback>b__0()
11. ExitGames.Client.Photon.EnetPeer:DispatchIncomingCommands()
12. ExitGames.Client.Photon.PhotonPeer:DispatchIncomingCommands()
13. PhotonHandler:Update() (at Assets/Photon Unity Networking/Plugins/PhotonNetwork/PhotonHandler.cs:158)
14.  

The code is:


if(!PhotonNetwork.insideLobby)
{
this.JoinRandomRoomAfterOnLobby = true;
PhotonNetwork.LeaveRoom();
PhotonNetwork.JoinLobby();
return;
}


The Update Loop ends, and the Photon code takes over. It produces that error. I can't find this error on the internet anywhere. "OperationResponse 254: ReturnCode: -2"

 

This is no longer an issue. Photon must have fixed something on their server code.

 

I have the same problem, did you make anything else to make it work? I have the same Photon and Unity version as you.

 

It just kinda fixed itself one day.

I didn't do anything on my side.

 

This is more likely a timing-dependent issue. You should make sure the logic waits for specific callbacks, before your client calls JoinLobby or such.
In your case, 254 is a OperationCode. The class lists this as Leave. Maybe you tried to Leave, while not in a room.

 

You were right, the logic was the problem, thank you for the help.
