client.operate(wPolicy,myKey, Operation.add(bin1),Operation.add(bin2), Operation.add(bin3),Operation.add(bin4),Operation.add(bin5), Operation.add(bin6),Operation.add(bin7),Operation.add(bin8), Operation.add(bin9),Operation.add(bin10));

Hi,

Please look in server logs for a more detailed error message and post it here. Usually, it’s invalid namespace or bin name > 14 characters.

Thanks Petter
