I got the following error with bodyParser:

PayloadTooLargeError: request entity too large

at jsonParser (/root/server/node_modules/body-parser/lib/types/json.js:118:7)

the code is following

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

function setEntity(req, res) {
   // something....
}

module.exports = (app) => {

  const router = new express.Router();

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

  router.use('/set/', (req, res) => {
    setEntity(req, res);
  });

  return router;
};

It seems similar to this question

So I tried these 3 solutions.

1.

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

2.

app.use(bodyParser.json({limit: "50mb"}));
app.use(bodyParser.urlencoded({limit: "50mb", extended: true, parameterLimit:50000}));

3.

app.use(bodyParser.json({limit:1024*1024*20, type:'application/json'}));
app.use(bodyParser.urlencoded({extended:true,limit:1024*1024*20,type:'application/x-www-form-urlencoding' }));

but the result didn't change.

another setting is like below

nginx has this setting : client_max_body_size 200M;
data size is under 500kb (json).
express : 4.15.3
body-parser : 1.18.2

I have no idea why I can't change limit data size.

    I found *app.use(bodyParser.json());* on another file. And I could solve this problem with this line. Thanks. – ya90net May 14 '18 at 07:48

My issue was because I had

app.use(express.json())

and also

app.use(bodyParser.json({ limit: "50mb" }))

and

app.use(bodyParser.urlencoded({ limit: "50mb", extended: true, parameterLimit: 50000 }))

I solved it after removing app.use(express.json()). Hope it helps somebody with the same issue.

Controlling the maximum request body size will do the trick, however, you do not need body-parser anymore. Instead of using body-parser middleware, use the new Express implementation:

app.use(express.json({limit: '50mb'}));
app.use(express.urlencoded({limit: '50mb', extended: true, parameterLimit: 50000}));

You can find here the complete documentation.

None of them works for me I couldn't change the limit by writing these

app.use(express.urlencoded({ limit: "50mb", extended: true, parameterLimit: 50000 }))
app.use(express.json({ limit: "50mb", extended: true, parameterLimit: 50000 }))

You can change the limit from node_modules\body-parser\lib\types\json.js

? bytes.parse(opts.limit || '100kb') to  ? bytes.parse(opts.limit || '50mb')
