Question Leave a Voice and Text channel Error Message

Vivox login is also normal,
Channel access / other user access event normal operation confirmed.
When leaving the channel, the error occurred.
I haven't been able to figure out the current cause.
I am asking for help.

Channel Leave Code

Code (CSharp):

1.  
2. public void CurLeaveChannel()
3. {
4.             if (curChannelInfo.channelSession == null)
5.                 return;
6.  
7.             var state = curChannelInfo.channelSession.AudioState;
8.             if (state == ConnectionState.Disconnected || state == ConnectionState.Disconnecting)
9.                 return;
10.  
11.             Debug.Log("[Vivox] CurLeaveChannel : Start");
12.  
13.             if (curChannelInfo.channelSession != null && state == ConnectionState.Connected)
14.             {
15.                 var channelSession = loginSession.GetChannelSession(curChannelInfo.curJoinChannel);
16.  
17.                 if (channelSession == null)
18.                     return;
19.  
20.                 channelSession.Disconnect();
21.                 loginSession.DeleteChannelSession(curChannelInfo.curJoinChannel);
22.                 Debug.Log($"[Vivox] CurLeaveChannel : {curChannelInfo.curJoinChannel.Name}");
23.             }
24.             Debug.Log("[Vivox] CurLeaveChannel : End");
25. }
26.  

 

I think the problem is on line 21. Instead of

loginSession.DeleteChannelSession(curChannelInfo.curJoinChannel);

use

loginSession.DeleteChannelSession(channelSession);

and see if that works
