Firebase Hosting NodeJS Express App not working, times out a lot - firebase

Question

I have my big NodeJS app using Firebase, it was last modified in 2018. Since at that time i was learning firebase and firebase hosting from examples. index.js file kinda became huge, it contains routes as well as definitions of Firebase Functions. Currently i wanted to modularize it. So proceeded to upgrade Firebase and dependencies. Something new i had noticied is Firebase Emulators, currently firebase server command is not working. Firebase emulator:start seems to start the app but mostly times out like out of 30 attempts only once it works.
Version info
Firebase : 11.5.0
Below is the package.json in functions folder.
{
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"serve": "firebase emulators:start --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"engines": {
"node": "16"
},
"main": "index.js",
"dependencies": {

"express": "^4.16.3",

"firebase-functions": "^3.18.0"
},
"devDependencies": {
"firebase-functions-test": "^0.2.0"
},
"private": true
}
Below is the firebase.json, emulator key/value is the new one, rest all i had from 2018 and no changes.
{
"database": {
"rules": "database.rules.json"
},
"functions": {
"ignore": [

},
"ui": {

},
"functions": {

},
"database": {

}
}
}
After i do the firebase emulators:start
In the browser, i am getting
Timed out waiting for function to respond.
In the firebase-debug.log, i see below messages. It says BUSY at multiple places but not sure whats BUSY as it being run locally.

Please advise, if any dependencies need to be upgraded to downgraded.

Answer 1

I was stuck with this for nearly two days. So i did couple of things.
Uninstalled all the NPM Packages which i had installed globally and locally.
Reinstalled Firebase-admin, Firebase-Functions and also other packages which was outdated with #latest, locally in the app folder.
Was not sure if firebase-tools package is to be installed locally or globally as a standard as Google Docs has global keyword in and one of David Easts recent video he has installed it locally. But anyhow reinstalled globally.
Not much actually changed in my code.
Just restarted the computer all worked.
Update : There seem to be a known issue. Downgraded to 11.2.2
