What is the error type of this error so I can ignore it?

Here is an example of an error type within this library.

closeErr := new(websocket.CloseError)
if errors.As(err, closeErr) {
...
}

websocket.CloseError is an error type within this library.

So, what error type is returned when you receive the error failed to close WebSocket: received header with unexpected rsv bits set: true:true:true?

Currently there's no specific error type when this happens, it's a plain fmt.Errorf error. Could you share a bit more context as to why this is happening and why you consider the error to be OK to ignore?

This error happens when you attempt to close a connected websocket.

Here is the code that causes this error (when the error is not ignored).

disconnect() closes a websocket: https://github.com/switchupcb/disgo/blob/v10/wrapper/session_routine_manager.go#L267

disconnect() definition: https://github.com/switchupcb/disgo/blob/v10/wrapper/session_routine_manager_actions.go#L298

It is OK to ignore because my code works when I ignore it.
