Can't start Emulator UI with node 18.16.0 [/firebase/emulators/ui-v1.11.5/server/server.js:569 re"use strict";]

[imabot2]

Maybe the same problem as this issue

Describe the bug
I can't start the emulator

To Reproduce
Run on Ubuntu 22.04 LTS
5.19.0-40-generic #41~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Mar 31 16:00:14 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Node is installed with Volta
node -v => v18.16.0
npm -v => 9.5.1
firebase tools --version => 11.28.0

I think everything is installed properly, I can deploy and runfirebase emulators:start --only functions

When I run the emulator:

$ firebase emulators:start --debug

Having trouble? Try firebase [command] --help

It try to clear the cache with rm -rf ~/.cache/firebase. That did not solve the problem.

I suspect a bug with node@18.16.0 because it works when I downgrade to node@16.20.0

Thanks. When released, how do I update to the last version? npm update -g firebase-tools ?

@imabot2 yes, or you can just do npm update -g firebase-tools.

In the meantime you can disable the ui in your firebase.json:

"ui": {
  "enabled": false
}

or removing the ~/.cache/firebase/emulators/ui-v1.6.4 and manually unzipping ~/.cache/firebase/emulators/ui-v1.6.4.zip

Downgrading the node to v18.15, remove .cache/firebase and re-run once more. This should work, at least that's what i was doing.

@Durisvk do you know when will be the fix become official release?
