Records not inserting - mySql Node - mysql

Question

The Task
I am trying read all the records from one table, and insert them into another table. I will re-use these functions later on in the app.
The Problem
The data doesn't appear to be being passed correctly. I am not getting any errors, yet the records are not inserted.
I debugged the data variable, and all the records are consoled correctly. For some reason, I am losing them when I call my insertData function.
Note: My table name is results, which may be a little confusing. I may change that in the future.
Entire Source Code
var mysql = require('mysql');
var connection = mysql.createConnection({
host: "localhost",
user: "root",
password: "",
database: "marketplace"
});
connection.connect(function (err) {
if (err) throw err;
console.log("Connected!");
})
const getData = function (tblName) {
var data = {};
switch (tblName) {
case "results":
sql = "SELECT * FROM results";
break;
case "items":
sql = "SELECT * FROM items";
break;
default:
sql = "SELECT * FROM results";
break;
}
return new Promise(resolve => {
connection.query(sql, function (err, results) {
if (err) {
console.log(err);
} else {
data.numResults = results.length;
data.data = results;
resolve(data);
}
})
})
}
const insertData = function (tbl, entity) {
return new Promise(resolve => {
var sql = `INSERT INTO ${tbl} (title,price,location,miles,imgUrl,itemURL) VALUES ?`;
var insertedIds = [];
for (var i = 0; i < entity.length; i++) {
connection.query(sql, entity[i], function (err, res) {
if (err) throw err;
insertedIds.push(res.insertId);
});
}
resolve(insertedIds);
})
}
const init = async function () {
var data = await getData("items");
console.log(data); // Works. Display all data
var insertSuccess = await insertData("results", data);
}
init();
