VSTHRD101 Avoid unsupported async delegates

[zimbres]

I have this code:

socket.OnConnected += async (sender, e) =>
{
    await socket.EmitAsync("login", (ack) =>
    {
        var result = JsonNode.Parse(ack.GetValue(0).ToString());
        if (result["ok"].ToString() != "true")
        {
            _logger.LogError("Uptime Kuma login failure");
        }
    }, data);
};

This code generates this Warning on VS.

This code is inside in a try catch block, but when some socket connection fail, the program crash with Unhandled exception:

Unhandled exception. System.Net.WebSockets.WebSocketException (0x80004005): The WebSocket is in an invalid state ('CloseSent') for this operation. Valid states are: 'Open, CloseReceived'

Is there something that I can change in my code or the function EmitAsync need to be changed according to receive a Func action instead of an Action?

Thanks!
