File upload scenarios with '413 Request Entity Too Large' in Express 4.x

express file-upload nginx javascript

Hey everyone, I'm running into an issue that's driving me crazy. I'm currently working on an Express.js application (version 4.17.1) where I allow users to upload files. However, whenever I attempt to upload files larger than 1MB, I'm working with a '413 Request Entity Too Large' behavior. I've tried adjusting the body-parser settings to accommodate larger files, but it doesn't seem to resolve the scenario. In my `app.js`, I have the following configuration: ```javascript const express = require('express'); const bodyParser = require('body-parser'); const app = express(); // This is where I set the limit, but it doesn't seem to help app.use(bodyParser.json({ limit: '10mb' })); app.use(bodyParser.urlencoded({ limit: '10mb', extended: true })); app.post('/upload', (req, res) => { // Handle file upload console.log(req.body); res.send('File uploaded successfully!'); }); const PORT = process.env.PORT || 3000; app.listen(PORT, () => { console.log(`Server is running on port ${PORT}`); }); ``` I've also checked my Nginx configuration (which acts as a reverse proxy) and set the `client_max_body_size` directive in my `nginx.conf`: ```nginx http { client_max_body_size 10M; } ``` After updating Nginx, I restarted the service, but I'm still experiencing the same behavior. I ensure that my uploads aren't being intercepted by any other middleware before they hit the `/upload` route. Can anyone guide to troubleshoot this scenario? Is there something I'm missing in either my Express server or Nginx configuration? Any insights or suggestions would be greatly appreciated.
