[remote_config] Filter out exceptions from the SDK

[vlazdra]

What feature would you like to see?

At the moment there is no way of filtering issues that arise from the SDK specifically from Remote Config. So, because of that the SDK issues an exception that get's reported by Sentry.
Now the problem with that is that I can' control that and because of that more than 30k events are generated per month towards Sentry. Since it's a paid service, I will like to filter out some of those exceptions and not have them all reported to Sentry.

How would you use it?

Filter out exceptions that Remote Config SDK is throwing.

Note: This was first reported towards the Flutter SDK instead, but they have confirmed that they won't change anything unless the native SDK supports it.
Reference issue reported to Firebase Remote Config for Flutter: firebase/flutterfire#10904

Hi @vlazdra, thanks for reaching out. I'd like to get some clarification regarding this feature. Wouldn't using the Filtering feature by Sentry enough to control the events being sent in order to avoid exceeding the limits?

Hey @argzdev, that would help yes, but it's rough around the edges a bit.

I do believe it could be achieved like this:

FutureOr<SentryEvent?> _beforeSend(SentryEvent event, {Hint? hint}) async {
  if (event.throwable != null && event.throwable is FirebaseException) {
    return null;
  } else {
    return event;
  }
}

But that would require me to check for the instance type and later do a string comparison of what the specifics of the Exception are.
Like for example, maybe I would like to omit FirebaseException [firebase_remote_config/internal] cancelled but still have FirebaseException [firebase_remote_config/internal] A data connection is not currently allowed. (just an example) I would need to do a String comparison that might break apart if the underlying SDK decides to change the structure of the message.

To also add on this, Android and iOS might report issues differently, so I would need to do a double String comparison potentially. Good thing is that for Flutter the exception is singular type FirebaseException

Hope I managed to explain it a bit.

Ah yes, that does sound reasonable. Thanks for clarifying, While we can't promise any timeline for this feature, our engineers will take a look into it once they have the time. if you have a code implementation strategy that you have in mind of how you'd use this feature, let us know. Thanks!

Also for others who find this useful, adding an emoji thumbs up on the original post can help our engineers prioritize adding this to the roadmap.

Hey @vlazdra. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!
