Rangeerror: invalid status code: 0

Question

See more:

I have following code:

var http = require('http');
var express = require('express');
var bodyParser = require('body-parser');

var port = process.env.port || 1337;

var app = express();
app.use(bodyParser.urlencoded({ 
    extended: true
}));

app.get('/', function (request, response) {
    response.sendFile(__dirname + "/views/MoviesList.html");
});

app.get('/api/list', function (request, response) {
    response.status(200).json(
        { "movieId": 1, "name": "The Pacific Rim" },
        { "movieId": 2, "name": "Transformer" });
});

app.listen(port);

I am getting following error in browser when I visit "http://localhost:1337/api/list"

"RangeError: Invalid status code: 0"

It also gave warning in node that res.json(status, obj) is deprecated use res.status(200).json(obj) instead. What mistake I am making here? Can anyone please help?

What I have tried:

I tried many solution provided from codeproject, solution was implemented as per codeproject posts, but still I am getting above error & deprecated message.

Solution 1

Please open local host private browser pr
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.

I have change the code like this

response.status(response.statusCode >= 100 && response.statusCode < 600 ? err.code : 500).json(
{ "movieId": 1, "name": "The Pacific Rim" },
{ "movieId": 2, "name": "Yeh Jawani Hai Deewani" });

Its still end up landing on err.code result

<pre lang="Javascript">var http = require('http');
var express = require('express');
var bodyParser = require('body-parser');

var port = process.env.port || 1337;

var app = express();
app.use(bodyParser.urlencoded({
extended: true
}));

app.get('/', function (request, response) {
response.sendFile(__dirname + "/views/MoviesList.html");
});

app.get('/api/list', function (request, response) {
response.status(response.statusCode >= 100 && response.statusCode < 600 ? err.code : 500).json(
{ "movieId": 1, "name": "The Pacific Rim" },
{ "movieId": 2, "name": "Yeh Jawani Hai Deewani" });
});

app.listen(port);</pre>
