Como inserir vários registros no Oracle DB usando Node.js

create table things (
  id   number not null,
  name varchar2(50) not null
)
/

var oracledb = require('oracledb');
var config = require('./dbconfig');
var things = [];
var idx;

function getThings(count) {
  var things = [];

  for (idx = 0; idx < count; idx += 1) {
    things[idx] = {
      id: idx,
      name: "Thing number " + idx
    };
  }

  return things;
}

// Imagine the 'things' were fetched via a REST call or from a file.
// We end up with an array of things we want to insert.
things = getThings(500);

oracledb.getConnection(config, function(err, conn) {
  var ids = [];
  var names = [];
  var start = Date.now();

  if (err) {throw err;}

  for (idx = 0; idx < things.length; idx += 1) {
    ids.push(things[idx].id);
    names.push(things[idx].name);
  }

  conn.execute(
    ` declare
        type number_aat is table of number

      begin
        forall x in l_ids.first .. l_ids.last
