CommandArgumentError { arg_idx: 0, kind: InvalidResultArity { result_idx: 0 } } in command 1

When transferring tokens, if there are many source objects, merge them first and then split the result into splitObjects. An error occurred during this step.

Argument splitCoin;
        if (sourceObjects.size() > 1) {
            Tuple3<ObjectID, SequenceNumber, ObjectDigest> destCoin = transactionBlock.getObjectRef(sourceObjects.get(0));
            List<Tuple3<ObjectID, SequenceNumber, ObjectDigest>> sourceCoins = sourceObjects.stream()
                    .skip(1)
                    .map(item -> transactionBlock.getObjectRef(item))
                    .collect(Collectors.toList());
            splitCoin = transactionBlock.mergeCoins(destCoin, sourceCoins);
        } else {
            splitCoin = transactionBlock.getObjectToArg(sourceObjects.get(0));
        }

        // splitCoins
        Argument argument = transactionBlock.splitCoinsNumber(splitCoin, Lists.newArrayList(amount));
        SuiAddress.Builder recipientAddressBuilder = new SuiAddress.Builder();
        recipientAddressBuilder.value = transactionBlock.geAddressBytes(recipient);
        transactionBlock.transferObjects(Lists.newArrayList(argument),
                transactionBlock.pure(recipientAddressBuilder.build()));

===== mergeCoins =======
  public Argument mergeCoins(
      Tuple3<ObjectID, SequenceNumber, ObjectDigest> destCoin,
      List<Tuple3<ObjectID, SequenceNumber, ObjectDigest>> sourceCoins) {
    ImmOrOwnedObject.Builder objectBuilder = new ImmOrOwnedObject.Builder();
    objectBuilder.value = destCoin;
    Argument dcoin = obj(objectBuilder.build());

    List<Argument> scoins =
        sourceCoins.stream()
            .map(
                objectRef -> {
                  ImmOrOwnedObject.Builder builder = new ImmOrOwnedObject.Builder();
                  builder.value = objectRef;
                  return obj(builder.build());
                })
            .collect(Collectors.toList());

    return mergeCoins(dcoin, scoins);
  }

I hope to get some advice.
