InvalidCastException when converting DiscordUser to DiscordMember

See original GitHub issue


System.InvalidCastException when trying to cast DiscordUser to DiscordMember


.NET 5.0 Windows 10 DSharpPlus 4.0.0

[Error] Exception occured
System.InvalidCastException: Unable to cast object of type 'DSharpPlus.Entities.DiscordUser' to type 'DSharpPlus.Entities.DiscordMember'.
   at dcBot.Run.Bot.OnVoiceState(DiscordClient sender, VoiceStateUpdateEventArgs e) in C:\Users\lukas\RiderProjects\discord\bot\Run\Main.cs:line 219
   at Emzi0767.Utilities.AsyncEvent`2.InvokeAsync(TSender sender, TArgs e, AsyncEventExceptionMode exceptionMode)

Steps to reproduce

Add event to Client.VoiceStateUpdated, convert DiscordUser to DiscordMember using VoiceStateUpdateEventArgs property After and finally property User.

private Task OnVoiceState(DiscordClient sender, VoiceStateUpdateEventArgs e)
            var member = (DiscordMember) e.After.User;
            return Task.CompletedTask;


It’s working like 50% of the time when i join or leave a channel it throws an error but when my friend joins it works. Funny thing that yesterday it didnt work with both of us.

Do you have the proper intents enabled on your dashboard and DiscordConfiguration? When I had my guild member and presence intents enabled I had no issues, however the moment I turned them off I started to receive this exception.
