lua - How to pass Array[Long] ids into Aerospike Record UDF? -

i store many sub records map in same top record, need remove sub records according passing keys, plan use udf implement it. when invoked java, log shows length 0. why? , how correct this? thanks!

in java =>

val ids = array(1,2,3) value.get(ids) 

in lua udf =>

function remove_keys(rec, binname, rmkeys)      info("value(%s) valtype(%s)",  tostring(rec), type(rec));     info("value(%s) valtype(%s)",  tostring(binname), type(binname));     info("value(%s) valtype(%s)",  tostring(rmkeys), type(rmkeys));      info("binname(%s)", binname)     info("len(%s)", tostring(#rmkeys))     ... end 

try:

string binname = "binname"; list<value> rmkeys = new arraylist<value>(); rmkeys.add(value.get("key1"));  client.execute(policy, key, packagename, "remove_keys", value.get(binname), value.get(rmkeys));
