how to handle root path request with node.js on firebase hosting?

Question

I'm developing web system using firebase hosting + functions. Inspite of specifying rewrite rules on firebase.json, a part of routing doesn't work.

root/
　├ functions/
　│  ├index.js
　│  ├routes/
　│  │  └ index.js
　│  └views/
　│    ├ index.jade
　│    └ sub.jade
　└ public/
    └index.html // this is created by default. I don't want to use this.

This is my firebase.json

"rewrites": [{
      "source": "**",
      "function": "app"
    }],

And this is node.js code.

router.get('/', function(req, res, next) {
    res.render('index');
});

router.get('/subdir', function(req, res, next) {
    res.render('sub');
});

result

https://myurl/ -> public/index.html is shown.(not handled on node.js)
https://myurl/ -> handled on node.js

Do you know how to handle root path request with node.js on firebase hosting.

See https://firebase.google.com/docs/hosting/full-config#hosting_priority_order .

Priority order of Hosting responses

The different Firebase Hosting configuration options described on this page can sometimes overlap. If there is a conflict, Hosting determines its response using the following priority order:

1. Reserved namespaces that begin with a /__/* path segment
2. Configured redirects
3. Exact-match static content
4. Configured rewrites
5. Custom 404 page
6. Default 404 page

Exact-match static content is high priority order than Configured rewrites.

So https://myurl/ get static content /index.html.

Can you try remove public/index.html?
