Suggested change
expPackets = []*types.IdentifiedPacketFee{}
expPackets = []types.IdentifiedPacketFee{}

You can make this a slice of values instead of pointers too and avoid the dereference on L:127

@colin-axner spoke with damian offline and did not change this as I'm using expPackets later to compare with the grpc response. It makes sense to keep it as is.

expPackets = append(expPackets, fee1, fee2, fee3)
expPackets = append(expPackets, &fee1, &fee2, &fee3)

@colin-axner @damiannolan should I just update the queries to no longer return a pointer as well?

The grpc query server endpoints will always use a pointer req/resp type. I'm not sure there's anyway to not do that, unless there's some gogoproto magic. But all of the grpc queries in ibc-go/sdk return pointer response types afaik so best to keep it consistent.
