Firebase-tools: 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.

@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.

[samtstern]

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

[dave-k]

@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]

Thank you for all of your information and patience here. You've been super helpful so far.

So in the debug log I don't see Dev App Server is now running which means for some reason the java command we launch from inside the emulator suite is not running the same as the one you ran for me. Here's the last useful line:

[debug] [2020-06-20T02:42:41.242Z] Starting Firestore Emulator with command {"binary":"java","args":["-Duser.language=en","-jar","/Users/dkennedy/.cache/firebase/emulators/cloud-firestore-emulator-v1.11.4.jar","--host","0.0.0.0","--port",8080,"--rules","/Users/dkennedy/project-2/firebase/quickstart-nodejs/firestore-emulator/javascript-quickstart/firestore.rules"],"optionalArgs":["port","webchannel_port","host","rules","functions_emulator","seed_from_export"],"joinArgs":false} {"metadata":{"emulator":{"name":"firestore"},"message":"Starting Firestore Emulator with command {\"binary\":\"java\",\"args\":[\"-Duser.language=en\",\"-jar\",\"/Users/dkennedy/.cache/firebase/emulators/cloud-firestore-emulator-v1.11.4.jar\",\"--host\",\"0.0.0.0\",\"--port\",8080,\"--rules\",\"/Users/dkennedy/project-2/firebase/quickstart-nodejs/firestore-emulator/javascript-quickstart/firestore.rules\"],\"optionalArgs\":[\"port\",\"webchannel_port\",\"host\",\"rules\",\"functions_emulator\",\"seed_from_export\"],\"joinArgs\":false}"}}

[info] i  emulators: Shutting down emulators. {"metadata":{"emulator":{"name":"hub"},"message":"Shutting down emulators."}}

So the command it's trying to run is:

java -Duser.language=en \
  -jar /Users/dkennedy//.cache/firebase/emulators/cloud-firestore-emulator-v1.11.4.jar \
  --host "0.0.0.0" --port 8080 \
  --rules /Users/dkennedy/project-2/firebase/quickstart-nodejs/firestore-emulator/javascript-quickstart/firestore.rules

I guess the last thing to try here is running that exact command, maybe the rules file is somehow changing the result? Again I apologize for basically blind debugging this, I just can't reproduce this myself.

We have the same issue with cloud-firestore-emulator-v1.11.2.jar. What's weirder, it works on one developer's laptop and not another. Same code, same versions of everything (including Java).

[Ross-Rawlins]

any news on this? I am getting this issue as well when importing a large data set on start up

[samtstern]

@Ross-Rawlins that sounds like a different issue since nobody above has mentioned import! For the issue above we have not been able to reproduce it ourselves, and we really can't fix an issue we can't reproduce (although we acknowledge that it's a real issue)

[beezital]

Same issue on my side running MacOS too.
It seems to be related to a networking condition involving java.
I have timed java -jar ~/.cache/firebase/emulators/cloud-firestore-emulator-v1.11.5.jar to be 31 seconds before it succeeds starting. Obviously this is too long when firebase emulators:start times out after 30 seconds.
I have a multi-WAN router establishing multiple network connections on different WANs (works great for standard browsing where fetching can happen in parallel). I have experienced other issues with this setup and involving java.
Workaround
So I tunneled my Mac's Internet access through a VPN and now java -jar ~/.cache/firebase/emulators/cloud-firestore-emulator-v1.11.5.jar starts instantaneously. And so does firebase emulators:start.

[handersonc]

Same issue here when I run firebase emulators:start --only firestore --import=./backupfolder

i emulators: Starting emulators: firestore
i firestore: Detected non-emulator Firestore export at backupfolder
i firestore: Importing data from backupfolder/mybackup.overall_export_metadata
i firestore: Firestore Emulator logging to firestore-debug.log
i emulators: Shutting down emulators.
i firestore: Stopping Firestore Emulator
i hub: Stopping emulator hub

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

[dracomithril]

So I was fighting with that thing for some time checking every possibility and the I did

npm install -g firebase-tools

and surprise surprise it started working 🤷 why bits me but maybe it will help someone

[ScottPierce]

I'm having this same problem in Docker Ubuntu environments trying to run CI tests. This morning, it just kept failing left and right for some reason:

yarn run v1.22.5
$ cd firebase && firebase emulators:exec --only firestore "cd .. && yarn test"
⚠  emulators: You are not currently authenticated so some features may not work correctly. Please run firebase login to authenticate the CLI.
i  emulators: Starting emulators: firestore
i  firestore: Firestore Emulator logging to firestore-debug.log
i  emulators: Shutting down emulators.
i  firestore: Stopping Firestore Emulator
i  hub: Stopping emulator hub

Error: TIMEOUT: Port 8080 on 0.0.0.0 was not active within 30000ms

[dracomithril]

Did you add FIREBASE_TOKEN as env variable as it's mentioned in documentation ?

[ScottPierce]

@dracomithril I don't think that's necessary to run tests. My current theory is that the computer that was running the build was constrained on resources, creating a slow startup time. We started seeing tests time out also. I reduced the number of parallel builds running on the server at one time, and haven't seen it since.

[dracomithril]

one probably odd question why

cd firebase && firebase emulators:exec --only firestore "cd .. && yarn test"

and not

"scripts": {
    ...
    "test": "firebase emulators:exec --only firestore jest"
  },

and regarding FIREBASE_TOKEN
You are not currently authenticated so some features may not work correctly. Please run firebase login to authenticate the CLI.
in my case it helped 🤷

[ScottPierce]

one probably odd question why

Because yarn test is the following script:

nx run-many --all --target=test --parallel --maxParallel 3

The above command is fairly complicated, and instead of duplicating it in multiple places, I'd rather centralize it into one place.

You are not currently authenticated so some features may not work correctly. Please run firebase login to authenticate the CLI.
in my case it helped 🤷

This is unlikely to be the solution. It's likely the issue is still there, and it's just intermittent. I still haven't set that, and yet everything is working for me again because I simply stopped running 2 build tasks at the same time on the machine, and limited it to one. That ensures the emulator starts up faster.

[brennengarland]

I've been having this same problem the last few days out of the blue. I'm running firebase emulators:start --import=data and the output is:

i  emulators: Starting emulators: auth, functions, firestore, database, hosting
!  functions: The following emulators are not running, calls to these services from the Functions emulator will affect production: pubsub
!  Your requested "node" version "10" doesn't match your global version "12"
i  firestore: Importing data from C:\repos\proctr\data\firestore_export\firestore_export.overall_export_metadata
i  firestore: Firestore Emulator logging to firestore-debug.log
i  emulators: Shutting down emulators.

i  firestore: Stopping Firestore Emulator
!  Firestore Emulator has exited upon receiving signal: SIGINT
i  hub: Stopping emulator hub

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

This problem persists if I change the ports.

[dracomithril]

@brennengarland did you changed node version?

! Your requested "node" version "10" doesn't match your global version "12"

If yes maybe try to reinstall all packages 🤔

[ScottPierce]

@brennengarland If you are running it on CI, then you might not have a fast enough CI container. Otherwise, I'd be looking at how large your data import is. If the import happens before the emulator is live, that could be why it's taking longer than 30 seconds.

[brennengarland]

@ScottPierce it looks independent of the data because when I run firebase emulators:start --only firestore I have the same issue. The issue from looking at wireshark, seems to be that port 8080 is setting a reset and ack flag on it's response, causing firebase to keep sending packets to try to open the port

[samhorlbeck]

Hi folks, this definitely sounds like a bug (tracked internally at b/172852315).
