Image Uploading scenarios with '413 Payload Too Large' scenarios in Next.js and Multer

next.js multer file-upload javascript

I'm wondering if anyone has experience with I've been banging my head against this for hours. I'm working on a Next.js application where I need to allow users to upload images. I'm using Multer for handling file uploads, and I have configured it to accept files up to 5MB. However, when I try to upload an image that exceeds this limit, I get a '413 Payload Too Large' behavior, which I understand means that the server is rejecting the request because the file size exceeds the configured limit. I've set up my Multer configuration as follows: ```javascript const multer = require('multer'); const upload = multer({ limits: { fileSize: 5 * 1024 * 1024 }, // 5MB limit storage: multer.memoryStorage() // Temporarily store in memory }); ``` In my API route, I'm using it like this: ```javascript export default function handler(req, res) { upload.single('image')(req, res, function (err) { if (err) { return res.status(400).json({ message: err.message }); } // Process the image here return res.status(200).json({ message: 'Image uploaded successfully' }); }); } ``` I also checked my Next.js configuration and ensured that I'm not missing any settings that would cause this scenario. My server is running on Node.js v16.13.0 and Next.js v12.0.7. I thought that returning a message when the limit is exceeded would be straightforward, but instead, I get the '413 Payload Too Large' behavior before it even hits my API logic. I've tried changing the limit in the Multer configuration and confirming that the limit is indeed being read correctly, but nothing seems to fix the scenario. Is there a way to correctly handle file size limits on image uploads in my Next.js application while providing feedback to users? I'm looking for best practices or potential workarounds to make this more user-friendly. For context: I'm using Javascript on macOS. What am I doing wrong? Could someone point me to the right documentation? Has anyone else encountered this?
