Answer by shellyyg for Error: request entity too large

I am using multer to upload files to AWS s3.For me, after adding client_max_body_size 100M; into nginx file,I get 400 error. (but the 413 error is gone, this means that it successfully went through nginx and reach your server)

My app.js file did not need to change, and remain like this, which works:

const express = require('express');const bodyParser = require('body-parser');app.use(bodyParser.json());app.use(bodyParser.urlencoded({ extended: true }));
