I have this working code. But after longtime when I rerun I am getting error. I am not sure Am I making mistake in running or what.



const express = require('express');  
const bodyParser = require('body-parser');
const url = require('url');
const querystring = require('querystring');
const fs = require('fs');
let {PythonShell} = require('python-shell')
let app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.get('/ip/predict', async function(req, res) {
let data = req.query.data;
console.log(data)

fs.writeFile("data.csv", data, function(err) {
if(err) {
return console.log(err);
}
});

var options = {
args: ['data']
}

PythonShell.run('my_script.py', options, function (err, results) {
if (err) throw err;
console.log('results: %j', results);
var pred = { "prediction":results }
res.send(pred)
});
});

let server = app.listen(8080, function() {
console.log('Server is listening on port 8080')
});


When I run this code using command



node app_express.js



it gives
