I am integrating the firebase with my react-native app, when I am adding the document, it give me this warning and didn't add the document.

Here is my config.js file code:

`import { initializeApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
apiKey: "my_project_api_key",
authDomain: "fir-auth-7be2f.firebaseapp.com",
projectId: "fir-auth-7be2f",
storageBucket: "fir-auth-7be2f.appspot.com",
messagingSenderId: "180812418171",
appId: "1:180812418171:web:88c2ff1f9e363ede8066de"
};

// Initialize Firebase
const app = initializeApp(firebaseConfig);
const auth = getAuth(app)
const db = getFirestore(app);

export { db, auth };
`

My Project Versions are:
firebase: "^9.16.0"
react: "18.2.0",
react-native: "0.71.0"

One thing to note that I am running my app on real device (not emulator) while coding and using cli.

when i register - the auth of firebase works fine but firestore db has no respne or respone after long time

in chrome console's i'm getting this :

This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

but my internet connection is greate...

for Lunar-Fang-coder : how to re-initialized it ?
just 'npm install firebase' or 'npm update' ? i tried that - didnt help me...

@urlsab Thanks for the logs. You are definitely having connectivity issues with the Firestore backend. Could you paste the entire output from https://debug-my.firebaseapp.com/ to https://gist.github.com/ and put the link here? Seeing the entire log will help diagnose.

@urlsab I'll take a closer look at your logs today or tomorrow. I'll ask my team for help if that doesn't prove fruitful. Then, I may ask for more information from you or suggest a workaround.

You are getting the strangest error I've ever seen: HTTP 418 "I'm a teapot"

https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/418

Is there perhaps a proxy between your device and Firestore that may be refusing the requests and returning the failed HTTP status 418?

Also, please test your app AND browse to https://debug-my.firebaseapp.com/ in the following environments (if possible):

  1. iOS real device
  2. iOS simulator
  3. Android real device
  4. Android emulator

Please reply with the information in a table like this:

Environment App behavior debug-my.firebaseapp.com behavior
iOS real device worked worked
iOS simulator Connection WebChannel transport errored HTTP 418
Android real device ... ...
Android emulator ... ...

Update: @Malik-Usman17 pointed out that you are not the OP. Sorry for getting that mixed up. For posterity, I've left my original comment intact below.

@urlsab In the opening comment, you mention that "I am running my app on real device (not emulator)" so some software running on your computer shouldn't affect the behavior on a real device, right? Also, what kind of "device" were you using (Android, iPhone)? Do you see this problem on the emulator/simulator as well as a real device?

I realize it will be a bit of work to put together the table that I asked for in a previous comment but that will greatly help narrow down the scope of the problem. As it is, all I see so far is that you get some confusing connectivity error and I'm trying to narrow down the source of the error to focus the investigation. And the debug web page may produce different results on the real devices and emulators, which will be useful information to help narrow down the problem.

In any case, I'll try to work with whatever information you're able to provide.

Infact that was me, that said it about the real device, I was running my app on android real device.

And can you please help in that below my comment

@Malik-Usman17 Oh you're right. I got the users mixed up. Thanks for correcting that.

When you say "I couldn't find the way to enable debug logging in react-native project" could you be more specific? Are you not able to invoke the setLogLevel() function? Do you invoke it, but can't see the log anywhere? Or do you invoke it and it throws an exception?

My colleague who is more familiar with react-native than me pointed out two potentially-useful resources.

If the problem is that you enable debug logging but don't see any logs, it appears that there was a range of react-native versions that failed to emit debug logs. If you're using RN 61+ then you should be good in this respect (https://stackoverflow.com/questions/46417066/react-native-console-debug-does-not-show-log-using-log-ios)

Another salient point is you have to use react-native log-ios or react-native log-android: https://stackoverflow.com/questions/30115372/how-to-do-logging-in-react-native

@urlsab I think that your issue is distinct from that reported by the OP. They have the same generic error but apparently different root causes. To avoid conflating two issues in this GitHub issue, please open a new issue for your problem. The information you provide in the new issue template will also be quite enlightening. Feel free to @mention me and I'll continue working with you.

I solved this error, but I didn't understand the core concept about it , well what I did it earlier were:

`import { initializeApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
apiKey: "my_api_key",
authDomain: "signal-app-clone-7d103.firebaseapp.com",
projectId: "signal-app-clone-7d103",
storageBucket: "signal-app-clone-7d103.appspot.com",
messagingSenderId: "120268271690",
appId: "1:120268271690:web:14fb83293caae9a504b6b3"
};

const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const db = getFirestore(app);

export { db, auth }`

So well somehow I find the solution and then turned my above firebase config file code the this:
`import { initializeApp } from "firebase/app";
import { getFirestore, initializeFirestore } from "firebase/firestore";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
apiKey: "my_api_key",
authDomain: "signal-app-clone-7d103.firebaseapp.com",
projectId: "signal-app-clone-7d103",
storageBucket: "signal-app-clone-7d103.appspot.com",
messagingSenderId: "120268271690",
appId: "1:120268271690:web:14fb83293caae9a504b6b3"
};

const app = initializeApp(firebaseConfig);

const auth = getAuth(app)

const db = initializeFirestore(app, {
experimentalForceLongPolling: true
})

export { db, auth };`

and it worked it, now I'm making the collection, adding the documents in a collection, getting documents or collections from firestore database all things working fine now.

thanks a lot @Malik-Usman17, and @dconeybe- thank you for your time.

Now we need to understand how simple method update changed all ?...and why it's not in firebase docs ?

Oh wow I would not have expected long polling to fix your issues. Good find! There must be a proxy between your apps and the Firestore servers that behaves in a way that we are not accustomed to. For full details about long polling, see #1674.

But here is the summary: normally Firestore clients open a long-lived connection with the Firestore server over HTTP port 80. This usually works; however, some proxy servers don't play well with long-lived HTTP connections. Long polling works around this by opening a new connection every 30 seconds to emulate a long-lived connection. So long polling is less efficient, but it is the only workaround we have for this problem, and it works quite well.

You can visually see the long polling if you open up the "network" tab of chrome (e.g. #1674 (comment)) as a new connection will open every 30 seconds.

Since everyone has reported that their presenting issues have been fixed by enabling long polling, I'm going to close this issue. Let me know if you think this issue should remain open.

I had the same issue, and it took me quite a while before I found this issue post. I'm using Expo, and the standard config works fine with ExpoGo. However, it started throwing "Could not reach Cloud Firestore backend" when I use Expo development build. The strange part is some Firestore api work while some don't. For those that didn't work, I had "Connection WebChannel transport errored", that led me to this post. Thanks to @Malik-Usman17, I can move on. I hope this can be put in the java SDK documentation.

I encountered this issue again and have a minimal reproduction code available.
If I run the same code on react in the browser it works, if I run it in react native on iOS simulator the timeout appears. If I try to add long polling I get a different error (in any case it cant be the reason, because it works from the same machine/network without long-polling) @dconeybe happy to share my exact setup if useful.

It might have todo with the underlying network stack of the machine you are on?

If I run my react code on the iOS simulator in the browser it also works.
Maybe it could have something to do with the hermes JS engine? I will investigate

Update:
I built my app on iOS with hermes disabled.
However, even then I had no luck, neither with experimentalForceLongPolling nor without

BUT, when I use the debugger in chrome, it finally starts working (with experimentalForceLongPolling set to true, not without though)

using react-native 0.71.3 and firestore 9.17.2
