PayloadTooLargeError: request entity too large

Question

I got the following error with bodyParser:

PayloadTooLargeError: request entity too large at readStream (/root/server/node_modules/raw-body/index.js:155:17) at getRawBody (/root/server/node_modules/raw-body/index.js:108:12) at read (/root/server/node_modules/body-parser/lib/read.js:77:3) at urlencodedParser (/root/server/node_modules/body-parser/lib/types/urlencoded.js:116:5) at Layer.handle [as handle_request] (/root/server/node_modules/express/lib/router/layer.js:95:5) at trim_prefix (/root/server/node_modules/express/lib/router/index.js:317:13) at /root/server/node_modules/express/lib/router/index.js:284:7 at Function.process_params (/root/server/node_modules/express/lib/router/index.js:335:12) at next (/root/server/node_modules/express/lib/router/index.js:275:10) at jsonParser (/root/server/node_modules/body-parser/lib/types/json.js:118:7) at Layer.handle [as handle_request] (/root/server/node_modules/express/lib/router/layer.js:95:5) at trim_prefix (/root/server/node_modules/express/lib/router/index.js:317:13) at /root/server/node_modules/express/lib/router/index.js:284:7 at Function.process_params (/root/server/node_modules/express/lib/router/index.js:335:12) at next (/root/server/node_modules/express/lib/router/index.js:275:10) at initialize (/root/server/node_modules/passport/lib/middleware/initialize.js:53:5) at Layer.handle [as handle_request] (/root/server/node_modules/express/lib/router/layer.js:95:5) at trim_prefix (/root/server/node_modules/express/lib/router/index.js:317:13) at /root/server/node_modules/express/lib/router/index.js:284:7 at Function.process_params (/root/server/node_modules/express/lib/router/index.js:335:12) at next (/root/server/node_modules/express/lib/router/index.js:275:10) 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.

Answer 1

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.

Answer 2

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.
