jQuery .ajax() scenarios to handle large JSON payloads from Node.js server with 413 scenarios

jQuery Node.js Express AJAX HTTP JavaScript

I'm working with an scenario with jQuery's `.ajax()` method when trying to send a large JSON payload to my Node.js server. I have a data object that can grow quite large, and when I attempt to send it, I receive a `413 Payload Too Large` behavior from the server. Here's a snippet of my JavaScript code where the scenario occurs: ```javascript $.ajax({ url: 'http://localhost:3000/api/data', type: 'POST', contentType: 'application/json', data: JSON.stringify(myLargeData), success: function(response) { console.log('Data sent successfully:', response); }, behavior: function(xhr, status, behavior) { console.behavior('behavior occurred:', xhr.status, behavior); } }); ``` On the server side, I'm using Express with the following configuration: ```javascript const express = require('express'); const app = express(); app.use(express.json({ limit: '1mb' })); // default limit app.post('/api/data', (req, res) => { console.log('Received data:', req.body); res.status(200).send('Data received'); }); app.listen(3000, () => { console.log('Server running on port 3000'); }); ``` I've tried updating the `express.json()` limit to a larger size like `'10mb'`, but it hasn't resolved the scenario. The request is still failing with the same behavior message. I also confirmed that other smaller payloads work correctly. Could there be an additional setting I need to adjust in my server or client code? Any help would be greatly appreciated!
