I too faced that issue  I was making a silly mistake by repeating the app use bodyParser json    like below   app use bodyParser json    app use bodyParser json   limit   50mb        by removing app use bodyParser json     solved the problem

I don t think this is the express global size limit  but specifically the connect json middleware limit  This is 100kb by default when you use express bodyParser   and don t provide a limit option   Try   app post   api 0 1 people   express bodyParser  limit   5mb     yourHandler

Little old post but I had the same problem

Using express 4.+ my code looks like this and it works great after two days of extensive testing.

var url         = require('url'),
    homePath    = __dirname + '/../',
    apiV1       = require(homePath + 'api/v1/start'),
    bodyParser  = require('body-parser').json({limit:'100mb'});

module.exports = function(app){
    app.get('/', function (req, res) {
        res.render( homePath + 'public/template/index');
    });

    app.get('/api/v1/', function (req, res) {
        var query = url.parse(req.url).query;
        if ( !query ) {
            res.redirect('/');
        }
        apiV1( 'GET', query, function (response) {
            res.json(response);
        });
    });

    app.get('*', function (req,res) {
        res.redirect('/');
    });

    app.post('/api/v1/', bodyParser, function (req, res) {
        if ( !req.body ) {
            res.json({
                status: 'error',
                response: 'No data to parse'
            });
        }
        apiV1( 'POST', req.body, function (response) {
            res.json(response);
        });
    });
};

User · Answer

for me following snippet solved the problem   var bodyParser   require  body-parser    app use bodyParser json  limit   50mb

User · Answer

In my case it was not enough to add these lines :

var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));

I tried adding the parameterLimit option on urlencoded function as the documentation says and error no longer appears.

The parameterLimit option controls the maximum number of parameters that are allowed in the URL-encoded data. If a request contains more parameters than this value, a 413 will be returned to the client. Defaults to 1000.

Try with this code:

var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: "50mb"}));
app.use(bodyParser.urlencoded({limit: "50mb", extended: true, parameterLimit:50000}));

I had the same error recently  and all the solutions I ve found did not work   After some digging  I found that setting app use express bodyParser  limit   50mb      did set the limit correctly    When adding a console log  Limit file size    limit   in node modules express node modules connect lib middleware json js 46 and restarting node  I get this output in the console    Limit file size  1048576 connect multipart   will be removed in connect 3 0 visit https   github com senchalabs connect wiki Connect-3 0 for alternatives connect limit   will be removed in connect 3 0 Limit file size  52428800 Express server listening on port 3002   We can see that at first  when loading the connect module  the limit is set to 1mb  1048576 bytes   Then when I set the limit  the console log is called again and this time the limit is 52428800  50mb   However  I still get a 413 Request entity too large   Then I added console log  Limit file size    limit   in  node modules express node modules connect node modules raw-body index js 10 and saw another line in the console when calling the route with a big request  before the error output      Limit file size  1048576   This means that somehow  somewhere  connect resets the limit parameter and ignores what we specified  I tried specifying the bodyParser parameters in the route definition individually  but no luck either   While I did not find any proper way to set it permanently  you can  patch  it in the module directly  If you are using Express 3 4 4  add this at line 46 of node modules express node modules connect lib middleware json js    limit   52428800     for 50mb  this corresponds to the size in bytes   The line number might differ if you don t run the same version of Express  Please note that this is bad practice and it will be overwritten if you update your module   So this temporary solution works for now  but as soon as a solution is found  or the module fixed  in case it s a module problem  you should update your code accordingly   I have opened an issue on their GitHub about this problem    edit - found the solution   After some research and testing  I found that when debugging  I added app use express bodyParser  limit   50mb       but after app use express json      Express would then set the global limit to 1mb because the first parser he encountered when running the script was express json    Moving bodyParser above it did the trick   That said  the bodyParser   method will be deprecated in Connect 3 0 and should not be used  Instead  you should declare your parsers explicitly  like so    app use express json  limit   50mb      app use express urlencoded  limit   50mb        In case you need multipart  for file uploads  see this post    second edit   Note that in Express 4  instead of express json   and express urlencoded    you must require the body-parser module and use its json   and urlencoded   methods  like so   var bodyParser   require  body-parser    app use bodyParser json  limit   50mb      app use bodyParser urlencoded  limit   50mb   extended  true       If the extended option is not explicitly defined for bodyParser urlencoded    it will throw a warning  body-parser deprecated undefined extended  provide extended option   This is because this option will be required in the next version and will not be optional anymore  For more info on the extended option  you can refer to the readme of body-parser    third edit   It seems that in Express v4 16 0 onwards  we can go back to the initial way of doing this  thanks to  GBMan for the tip    app use express json  limit   50mb      app use express urlencoded  limit   50mb

The following worked for me    Just use   app use bodyParser  limit   50mb        that s it   Tried all above and none worked  Found that even though we use like the following   app use bodyParser     app use bodyParser  limit   50mb      app use bodyParser urlencoded  limit   50mb        only the 1st app use bodyParser     one gets defined and the latter two lines were ignored   Refer  https   github com expressjs body-parser issues 176    see  dougwilson commented on Jun 17  2016

In my case the problem was on Nginx configuration  To solve it I have to edit the file   etc nginx nginx conf and add this line inside server block   client max body size 5M    Restart Nginx and the problems its gone  sudo systemctl restart nginx

The better use you can specify the limit of your file size as it is shown in the given lines:

app.use(bodyParser.json({limit: '10mb', extended: true}))
app.use(bodyParser.urlencoded({limit: '10mb', extended: true}))

You can also change the default setting in node-modules body-parser then in the lib folder, there are JSON and text file. Then change limit here. Actually, this condition pass if you don't pass the limit parameter in the given line app.use(bodyParser.json({limit: '10mb', extended: true})).

A slightly different approach - the payload is too BIG

All the helpful answers so far deal with increasing the payload limit. But it might also be the case that the payload is indeed too big but for no good reason. If there's no valid reason for it to be, consider looking into why it's so bloated in the first place.

Our own experience

For example, in our case, an Angular app was greedily sending an entire object in the payload. When one bloated and redundant property was removed, the payload size was reduced by a factor of a 100. This significantly improved performance and resolved the 413 error.

For express  4 16 0  express json with limit works directly  app use express json  limit   50mb

User · Answer

I faced the same issue recently and bellow solution workes for me.

Dependency : 
express >> version : 4.17.1
body-parser >> version": 1.19.0

const express = require('express');
const bodyParser = require('body-parser');

const app = express(); 
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));

For understanding : HTTP 431

The HTTP 413 Payload Too Large response status code indicates that the request entity is larger than limits defined by server; the server might close the connection or return a Retry-After header field.

If you are using express json   and bodyParser together it will give error as express sets its own limit   app use express json     app use express urlencoded   extended  false        remove above code and just add below code  app use bodyParser json   limit   200mb       app use bodyParser urlencoded   limit   200mb    extended  true  parameterLimit  1000000

in my case    setting parameterLimit 50000 fixed the problem  app use  bodyParser json  limit   50mb       app use bodyParser urlencoded     limit   50mb     extended  true    parameterLimit 50000
