It might make sense to put this function underneath KeyForwardRealyerAddress (or at least that's how I was organizing the code). Open to other suggestions

keySplit := strings.Split(key, "/")
if len(keySplit) != 4 {
return channeltypes.PacketId{}, sdkerrors.Wrapf(
sdkerrors.ErrLogic, "key provided is incorrect: the key split has incorrect length, expected %d, got %d", 4, len(keySplit),
)

nit: It might be easier to understand this case if you just wrote a raw string. e.g. "transfer/channel-9"

actually i realised i should used the KeyForwardRelayerAddress anyway in this function --

yup, since otherwise it won't pass the length check
