I reproduce the 404 error using your code, and noticed that you use next.js project, which is a little different in Azure between local.
You need two file: server.js and web.config, and modify package.json like below. I test with your code, and it works perfect on my side.
package.json modify.
"scripts": {
"dev": "node server.js",
"build": "next build",
"start": "node server.js"
server.js (create this file with the code below:)
const { createServer } = require('http')
const next = require('next')
const port = parseInt(process.env.PORT, 10) || 3000
const dev = process.env.NODE_ENV !== 'production'
const app = next({ dev })
const handle = app.getRequestHandler()
app.prepare().then(() => {
createServer((req, res) => {
const parsedUrl = new URL(req.url, 'http://w.w')
const { pathname, query } = parsedUrl
if (pathname === '/a') {
app.render(req, res, '/a', query)
} else if (pathname === '/b') {
app.render(req, res, '/b', query)
} else {
handle(req, res, parsedUrl)
}
}).listen(port, (err) => {
if (err) throw err
console.log(`> Ready on http://localhost:${port}`)
})
})
web.config (create this file with the code below:)
<?xml version="1.0" encoding="utf-8"?>

You can control how Node is hosted within IIS using the following options:
* watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
* node_env: will be propagated to node as NODE_ENV environment variable
* debuggingEnabled - controls whether the built-in debugger is enabled
See https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/web.config for a full list of options

Refer to: unable to deploy next js to azure
This is the steps I did:
Pre: Add web.config and server.js and modify package.json.
1. Create build pipeline.
2. Create release pipeline.
3. Run build-->trigger publish.
Download and check the artifacts:
- Check the web app deployed in Azure.
