[URGENT]: PayloadTooLargeError: request entity too large

[SebghatYusuf]

Bug report

Describe the bug

I'm trying to send a payload using POST method to a custom endpoint, and I get PayloadTooLargeError how to extend the default size limit if this is not a bug?

System information

Medusa version (including plugins):
Node.js version:v16.20.0
Database: postgresql
Operating system: macOS 13
Browser (if relevant):

Steps to reproduce the behavior

1. Create a custom endpoint
2. Send a post request with a payload more than 1 MB

Expected behavior

There should be a way to extend the post method payload limit.

Code snippets

I tried to pass limit to body parser json function but didn't resolve the issue.

router.post("/customizer/design", json({ limit: '5mb' }), wrapHandler(async (req, res) => {
    const service: CustomDesignService = req.scope.resolve('customDesignService');
    const stat = await service.create(req.body);

    res.status(200).json({
      status: "success",
      stat,
    });
  }));

@pevey, I knew that the problem was with the express server. Even though I was making changes to the index.js file in the base directory, I couldn't see any of the changes applied. This was because when you run medusa develop , it doesn't use the index.js server, causing my code to not work. To resolve the issue, I had to run index.js using node index.js .
Here is the modified index.js that resolved the issue, in case anyone else encounters this problem.

const { json, urlencoded } = require("body-parser");
const express = require("express")
const { GracefulShutdownServer } = require("medusa-core-utils")

const loaders = require("@medusajs/medusa/dist/loaders/index").default;

(async () => {
	async function start() {
		const app = express()
		app.use(json({ limit: '10mb' }))
		app.use(urlencoded({ limit: '10mb', extended: true }))

		const directory = process.cwd()

		try {
			const { container } = await loaders({
				directory,
				expressApp: app
			})

			const configModule = container.resolve("configModule")
			const port = process.env.PORT ?? configModule.projectConfig.port ?? 9000
			const server = GracefulShutdownServer.create(
				app.listen(port, (err) => {
					if (err) {
						return
					}
					console.log(`Server is ready on port: ${port}`)
				})
			)

			// Handle graceful shutdown
			const gracefulShutDown = () => {
				server
					.shutdown()
					.then(() => {
						console.info("Gracefully stopping the server.")
						process.exit(0)
					})
					.catch((e) => {
						console.error("Error received when shutting down the server.", e)
						process.exit(1)
					})
			}
			process.on("SIGTERM", gracefulShutDown)
			process.on("SIGINT", gracefulShutDown)
		} catch (err) {
			console.error("Error starting server", err)
			process.exit(1)
		}
	}

	await start()
})()
