Error: TIMEOUT: Port 8080 on localhost was not active within 30000ms

firebase-debug.log
Cloud Firestore emulator quickstart
I am getting the Timeout error running the emulators:exec command on an unchanged project.

I tried other ports 8081, 8082 and

$ sudo firebase emulators:exec --only firestore 'npm test'
$ firebase emulators:exec 'npm test'
$ firebase emulators:start

produced the same Timeout error.

./firebase/quickstart-nodejs/firestore-emulator/javascript-quickstart

macOS v 10.15.6

$ firebase --version
8.4.2
$ node --version
v14.4.0
$ 

$ firebase emulators:exec --only firestore 'npm test'
i  emulators: Starting emulators: firestore
i  firestore: Firestore Emulator logging to firestore-debug.log
i  emulators: Shutting down emulators.

@dave-k when you say "unchanged project" do you mean this was working before and has since stopped? I haven't seen an error like this on macOS yet, could you try two things:

1. I don't think anyone on our team is using Node 14 yet, most of us are on 12 or below. Does changing your Node version change anything?
2. If you change the host for the Firestore emulator to 0.0.0.0 instead of localhost does that change anything? You can set this in firebase.json alongside the port.

Oh also I'm gonna transfer this issue over to the Firebase CLI repo.

@samtstern Unchanged i.e. no changes made to the tests.

1. node v10.21.0
2. host: 0.0.0.0

Same Timeout error: [error] Error: TIMEOUT: Port 8080 on 0.0.0.0 was not active within 30000ms

@dave-k thanks for trying hose things ... I am still pretty stumped on this issue.

Could you try running the Firestore emulator JAR directly and see if it works for you:

java -jar ~/.cache/firebase/emulators/cloud-firestore-emulator-v1.11.4.jar

The exact version of the jar may vary but you should have a cloud-firestore-emulator-*.jar in that location. You can also pass --port=<number> if you don't want to use 8080.

@samtstern

$ java -jar ~/.cache/firebase/emulators/cloud-firestore-emulator-v1.11.4.jar
API endpoint: http://localhost:8080
If you are using a library that supports the FIRESTORE_EMULATOR_HOST environment variable, run:

   export FIRESTORE_EMULATOR_HOST=localhost:8080

Dev App Server is now running.
