RangeError: Invalid status code: 0

Question

I am having an issue where I am getting the following error code when attempting a POST request on this application (bearing in mind I am a beginner node.js/js programmer):

Error:

[20:22:28] [nodemon] starting `node app.js`

app.js:

var express = require('express');

var router = express.Router();

var app = express();

var bodyParser = require('body-parser');
app.use( bodyParser.json() );       // to support JSON-encoded bodies
app.use(bodyParser.urlencoded({     // to support URL-encoded bodies
    extended: true
}));

var path = require('path');

var port = process.env.PORT || 3000;

var index = require('./routes/index');
var edit = require('./routes/edit');

app.use('/', index);
app.use('/edit', edit);

app.use(express.static(path.join(__dirname, 'public')));

app.set('view engine', 'jade');

app.set('views', 'views');

app.listen(port, function (err) {
    console.log("Running server on", port);
});

module.exports = index;

The following is my edit.js route, where I believe the issue is occurring:

var express = require('express');

var router = express.Router();

var app = express();

var bodyParser = require('body-parser');
app.use( bodyParser.json() );       // to support JSON-encoded bodies
app.use(bodyParser.urlencoded({     // to support URL-encoded bodies
    extended: true
}));

var path = require('path');

var port = process.env.PORT || 3000;

var index = require('./routes/index');
var edit = require('./routes/edit');

app.use('/', index);
app.use('/edit', edit);

app.use(express.static(path.join(__dirname, 'public')));

app.set('view engine', 'jade');

app.set('views', 'views');

app.listen(port, function (err) {
    console.log("Running server on", port);
});

module.exports = index;

I assume this is an error within a callback, but I'm not sure. — Matt, Jun 27 '16 at 19:30
Can you update your question with the good code sample for `edit.js` ? Seems like you pasted `app.js` in it. — Jérôme, Jun 28 '16 at 12:22

I had a similar error message just now and managed to solve the problem by changing:

res.status(statusCode);

to:

if (statusCode >= 100 && statusCode < 600)
  res.status(statusCode);
else
  res.status(500);

or just:

res.status(statusCode >= 100 && statusCode < 600 ? err.code : 500);

I.e. make sure you aren't trying to set an invalid HTTP status code somewhere.

It's likely this is the issue but it looks like you've accidentally duplicated the app.js code instead of pasting the edit.js code in the question.

Thanks a lot! Saved me a lot of time :-) – Bala Abhinav Aug 04 '17 at 08:01
When used statusCode, it threw ReferenceError – Divya Galla Jan 05 '18 at 07:24
@DivyaGalla statusCode must be defined first. I.e. `var statusCode = 200;` Use whatever code is suitable for your situation. – Bavell Jan 16 '18 at 17:57

This case also happen when we have validation error on form save and we are using res.redirect instead of res.render method

for example-

Please Use

res.render('users/add', {
    countries: countries
});

instead of (it's wrong statement for node)

res.redirect('/users/add', {
    countries: countries
});

I had the same problem which I solved by using:

res.send('0')

instead of

res.send(0)

Yup! that's it! `res.send(String(result))` – Leandro Aug 03 '22 at 00:39

for me the issue was that i had not created my upload directory and it returns me the error. may be you should consider to create your ./upload directory first, because of permission issues on linux.
