NullReferenceException when using InteractivityExtension.WaitForEventArgsAsync<T>(Func<T, bool> predicate)

See original GitHub issue

Hello, these errors are occurring every time a user interacts with components “catched” by a InteractivityExtension.WaitForEventArgsAsync<T>(Func<T, bool> predicate):

[2021-10-17 02:02:12 -03:00] [104 /EventHandler] [Error] Event handler exception for event COMPONENT_INTERACTED thrown from System.Threading.Tasks.Task HandleEvent(DSharpPlus.DiscordClient, DSharpPlus.EventArgs.ComponentInteractionCreateEventArgs) (defined in DSharpPlus.Interactivity.EventHandling.EventWaiter`1[DSharpPlus.EventArgs.ComponentInteractionCreateEventArgs])
System.NullReferenceException: Object reference not set to an instance of an object.

I’m using the ComponentInteractionCreateEventArgs for the parameters T and p => p?.Message?.Id == msgId for the predicate.

The args is returned fine, but the log screen has a lot of these errors.

Just tried to reproduce this using the following code with no success (no errors on my side), does it still happen in the latest nightly version?

I believe this was fixed in #1230.

That’s a bit outdated (we’re at 4.3.0 nightlies now) but I don’t think there has been any change to it. I’ll look into it at some point
