[remote_config] internal remote config fetch error
Bug report
Describe the bug
Before we upgraded, I've never had this not happen to me. Strangely, my colleague never gets this on his device. Firebase throws every single time we call fetchAndActivate().
Here's the whole stacktrace
Task <C134C25B-109D-43EF-8FC5-CC663AB1CBD7>.<1> finished with error [-999] Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLStringKey=https://firebaseremoteconfig.googleapis.com/v1/projects/lessgo-dev/namespaces/firebase:fetch?key=AIzaSyAVEBJyZXrLWDTAHK5j092NMesJ-v1K9FY, NSLocalizedDescription=cancelled, NSErrorFailingURLKey=https://firebaseremoteconfig.googleapis.com/v1/projects/lessgo-dev/namespaces/firebase:fetch?key=AIzaSyAVEBJyZXrLWDTAHK5j092NMesJ-v1K9FY}

Steps to reproduce
final remoteConfig = RemoteConfig.instance;
await remoteConfig.setConfigSettings(RemoteConfigSettings(
fetchTimeout: const Duration(seconds: 20),
minimumFetchInterval: const Duration(minutes: 20),
));
await remoteConfig.fetchAndActivate(); // This bad boy throws
Additional context
This only started happening after we upgraded to Flutter 2 and adopted new Firebase package versions.

I tried the official plugin repo on latest stable (2.2.0) and with below dependencies, with which the fetchAndActivate() worked properly:
firebase_core: ^1.1.0
firebase_remote_config: ^0.10.0-dev.4

Not much I can add to that @darshankawar, like I said, it works 100% of the time on some devices, and breaks 100% of the time on other devices. It might have something to do with iOS persisting more than is good for it despite reinstalls (maybe from an old version of remote_config).
This is weird. Maybe somehow the requests are going more than once and previous request is getting cancelled by any chance, but this is just my guess.
Keeping this open for further investigation, as I am unable to replicate it.
I was able to reproduce this with.
[✓] Flutter (Channel stable, 2.0.6, on macOS 11.2.3 20D91 darwin-x64, locale en-TR)
and
firebase_remote_config: ^0.10.0
Here are steps to reproduce:
- Initialize the app with remote config
- Give it a custom RemoteConfigSettings e.g.
RemoteConfigSettings(
fetchTimeout: const Duration(seconds: 10),
minimumFetchInterval: const Duration(minutes: 5),
),
- Run the application on macOS as a Desktop application
- Wait for 5 minutes (or as long as your minimumFetchInterval)
- Close the application
- Reopen the app Actual:
- It gives the error. Expected:
- It should fetch the latest version of the information.
Happens to me on iOS with
[✓] Flutter (Channel stable, 2.2.3, on macOS 11.1 20C69 darwin-x64, locale en)
and
firebase_remote_config: ^0.10.0+2
If I remove RemoteConfigSettings from the initialization, it works. If I put it back in the code, it throws the exception again. This is the native iOS log:

Failed to submit an app to app store because on iPad it crashes with same error while tested by apple testers. Not crashing on my side. :(
I had a similar issue which I managed to solve when I was trying to wait for both futures simultaneously.
final List<Future<void>> setupFutures = [
RemoteConfig.instance.setConfigSettings(
RemoteConfigSettings(
fetchTimeout: Duration(seconds: 60),
minimumFetchInterval: Duration(seconds: 0),
),
);
RemoteConfig.instance.fetchAndActivate(),
];
await Future.wait(setupFutures);
Awaiting RemoteConfig.instance.setConfigSettings before calling RemoteConfig.instance.fetchAndActivate solved my issue.
@rubenvereecken I see that you are already doing this without succeeding but it might help someone else stumbling upon this issue.
It's honestly pretty wild that this package does this one very simple thing like managing a simple key-value dcument, yet this main use case hasn't been working for multiple months.
I had the same problem, and solved by checking the API KEY at the file GoogleService-info.plist
I restricted the Firebase API to IOS, but the GoogleService-info.plist was with the Android app API KEY.
A concrete cause of the "internal error" in case of CI failures was keychain sharing capability, so make sure to add it with com.firebase group
#6748 also propagates an underlying error description up to the dart code, so please, share those in case keychain sharing capability doesn't fix your problem
@lesnitsky why should we add our apps to the com.firebase group? That sounds like a security risk.
I managed to work around this error by doing the following:
await RemoteConfig.instance.activate();
// Only fetch after a delay to prevent an internal bug from occurring
// See https://github.com/FirebaseExtended/flutterfire/issues/6196
await Future.delayed(const Duration(seconds: 1));
await RemoteConfig.instance.fetchAndActivate();
Not sure how this would help but somehow adding the delay there fixes the issue
@Kavantix macOS apps prompt for keychain access (firebase SDK reads tokens from keychain). If you're ok with this behavior – no need to add a capability
your workaround doesn't seem to be related to the keychain at all
Also, it's hard to judge what exactly the issue is in each specific case because the error from native wasn't propagating before #6748 was merged.
My comment was related to a CI failure, other cases may have completely different root causes
@lesnitsky exactly it is not related to KeyChain, I'm experiencing it on iOS and android (not using macos for this app)
I can see the native error though, probably printed by the iOS sdk:
7.11.0 - [Firebase/RemoteConfig][I-RCN000026] RCN Fetch failure: Error Domain=NSURLErrorDomain Code=-999 "canceled" UserInfo={NSErrorFailingURLStringKey=https://firebaseremoteconfig.googleapis.com/v1/projects/{redacted}/namespaces/firebase:fetch?key={redacted}, NSErrorFailingURLKey=https://firebaseremoteconfig.googleapis.com/v1/projects/{redacted}/namespaces/firebase:fetch?key={redacted}, _NSURLErrorRelatedURLSessionTaskErrorKey=(

7.11.0 - [Firebase/RemoteConfig][I-RCN000026] RCN Fetch failure. Response http error code: 0
That is also why I tried the delay in the first place, looks like a timing issue to me
I made a mistake and ran fetchAndActivate twice in parallel which caused this issue. Maybe better error message or no-op on second call might help? This might explain why some people resolved this issue by adding a delay.
Repro code:
final config = RemoteConfig.instance;
await Future.wait([
config.fetchAndActivate(),
config.fetchAndActivate(),
]);
The (desperate) work-around by @Kavantix seems to point at a potential fix in the package.
@darshankawar @maheshmnj care to take a look?
This issue has passed primary triage and has been labeled for further investigation. Let us wait for the secondary triage's input.
I run into the same issue in one of my apps, the workaround that fixed it was this:
await InternetAddress.lookup('google.com');
await _remoteConfig.fetchAndActivate();
Also, adding a delay as suggested by @Kavantix works, not sure why but this is still reproducible in v2.0.0 only on iOS, works well on Android.
I had a similar issue which I managed to solve when I was trying to wait for both futures simultaneously.
final List<Future<void>> setupFutures = [ RemoteConfig.instance.setConfigSettings( RemoteConfigSettings( fetchTimeout: Duration(seconds: 60), minimumFetchInterval: Duration(seconds: 0), ), ); RemoteConfig.instance.fetchAndActivate(), ]; await Future.wait(setupFutures);Awaiting
RemoteConfig.instance.setConfigSettingsbefore callingRemoteConfig.instance.fetchAndActivatesolved my issue.@rubenvereecken I see that you are already doing this without succeeding but it might help someone else stumbling upon this issue.
This is not working on IOS
@darshankawar is there a solid workaround for this or an ETA for this fix? if it causes ios first install to fail to get remote config values then it would mean firebase remote config won't work for us at all like @lesnitsky but surely there is a reliable fix like @Kavantix etc mentioned. i tried both lookup google.com and ensureinitialized and I'm not having much luck so far.

Thank you so much!
In my case it wasn't as obvious, but the same issue.
I was calling setConfigSettings in the init method of my whole app, while calling fetchAndActivate() in another init method of the first route that's loaded. That would cause the same race condition and this completely unreadable error message.
