I'm having trouble while calling Polly.

Polly.synthesizeSpeech(params, (err, data) => { if (err) { console.log(err.code) } else if (data) { if (data.AudioStream instanceof Buffer) { Fs.writeFile(argv.mp3, data.AudioStream, (err)=> { if (err) { return console.log(err) } console.log("The file was saved!") var output = child_process.execSync('lame --decode ' + argv.mp3 + ' ' + '-b 8000' + ' ' + argv.wav + '.wav'); }) } } })

/opt/aws-nodejs-sample/node_modules/aws-sdk/lib/request.js:31
throw err;
^

I have no idea how to fix this.
