firebase-functions express.js path fix

index.js

const app = require('express')();

// define your routes, etc ...

exports.route = functions.https.onRequest((req, res) => {
	
	// https://some-firebase-app-id.cloudfunctions.net/route
	// without trailing "/" will have req.path = null, req.url = null
	// which won't match to your app.get('/', ...) route 
	
	if (!req.path) {
		
		// prepending "/" keeps query params, path params intact
		req.url = `/${req.url}`
	
	}
	
	return app(req, res)

});

@cdock1029 How did you point the hosting to the function? I'm doing:

{
    "hosting": {
        "public": "public",
        "rewrites": [{
            "source": "**",
            "function": "helloWorld"
        }]
    }
}

It doesnt' work for the index path. It only works for /** paths.
Is this part of this issue?

it is not working for the "**" as @flasd mentioned earlier
