node.js - using mysql in Electron -

-



im trying use mysql in electron i'm running error

typeerror: invalid data, chunk must string or buffer, not object   @ socket.write (net.js:667)   @ protocol.<anonymous> (connection.js:100)

with code

var mysql = require('mysql');  var con = mysql.createconnection({     host: 'host address',     user: 'username',     password: 'pw',     database: 'db name',   });  con.connect(err => {     if(err) throw err }) con.query('select * books', (err2, result) => {     if(err2) {         throw err2;     }     console.log(result); })

if paste test.js file , run node runs 100% fine without errors, im not sure im going wrong here

so turns issue had fact running angular on electron. if put code inside angular code error out if put in index.html run fine.
made little proxy function in index.html connecting db , making queries, i'd jsut call inside angular app without problem window.mysqlquery(querystring)
