@vmarkushin @blasrodri I think we also need to decode client state maybeDecodeWasmData in the querier function:

ibc-go/modules/core/02-client/keeper/grpc_query.go

Line 25 in 5e2c7ed

func (q Keeper) ClientState(c context.Context, req *types.QueryClientStateRequest) (*types.QueryClientStateResponse, error) {

and

ibc-go/modules/core/02-client/keeper/grpc_query.go

Line 100 in 5e2c7ed

func (q Keeper) ConsensusState(c context.Context, req *types.QueryConsensusStateRequest) (*types.QueryConsensusStateResponse, error) {
