Steps to reproduce:


Try to use iOS app in airplane mode and save and load data from firebasestore offline. The issue happens 1 in 4 especially if you start your app when the phone has been offline for a while!

Hi @mojikashani. Thank you for reporting this issue and my apologies that you are being affected by this crash. Firestore should definitely not be crashing your app just because the device is in airplane mode. I am going to try to reproduce by creating a simple app that writes to Firestore and launching it a bunch of times while offline.

In the meantime, could you help by providing some or all of the additional information requested below?

  1. Do you have a minimal app whose source code you could share with me that I could use to reproduce the crash?
  2. Do you have a stack trace for the exception? The last line of the logs you provided mention a FirestoreInternalError; however, a full stack trace, if available, would help pinpoint the error.
  3. Can you reproduce with debug logging enabled and provide those logs? To do this, set FirebaseFirestore.LogLevel to LogLevel.Debug after creating the FirebaseFirestore instance.

Thanks @dconeybe , This issue is happening especially when I am updating a document with the new data in offline mode:
Also as you mentioned, I set the Firestore Log Level to Debug and here is the logs:

Thank you for the additional logs. The fatal FirestoreInternalError is a result of an assertion failure somewhere in Firestore's code base. Strangely, there does not appear to be any "message" associated with the error, thus making it very difficult to pinpoint what may be going wrong. If you happen to be able to find a message somewhere else in the logs or some other logs that would be very helpful.

From the logs you provided, specifically, the log line beginning with "WriteStream (116314088) Stream error", I can see that the call to WriteStream.Start() is failing here: https://github.com/firebase/firebase-ios-sdk/blob/0dbff8aa84aafebb6a0322cb4d08fa6da1dbc16a/Firestore/core/src/remote/stream.cc#L299, which means that the call to credentials_provider_->GetToken(...) failed. I scanned the code around that line but could not find anything that I thought would result in a FirestoreInternalError (i.e. a call to HARD_ASSERT()).

Currently, I'm using a Firestore project that does not require authentication to try to reproduce this issue. I have not yet been able to reproduce. I'll try using a project that requires authenticated users and report back.

If you have time, one thing that you could do to help (which I would do if I could reproduce the crash) is to add a bunch of log messages into Firestore's source code to try and figure out which HARD_ASSERT() is failing. When you export your Unity project to an Xcode project you can edit Firestore's source code that is pulled down by pod. I would start by adding LOG_WARN messages into Pods/FirebaseFirestore/Firestore/core/src/remote/stream.cc and Pods/FirebaseFirestore/Firestore/core/src/remote/write_stream.cc, specifically the methods Start(), Close(), and NotifyStreamClose().

Update: I was able to reproduce the crash but the logs aren't very helpful. Luckily, another user has reported the same crash against the C++ SDK and the logs there are much more useful: firebase/firebase-cpp-sdk#182. I will continue investigation.

I have found the bug and a fix for this issue is currently in code review. Please see firebase/firebase-cpp-sdk#182 (comment) for more details, including a hacky workaround. I will keep this issue opened until the fix is submitted and ready for release.

Update: The fix has been submitted and will be included in the next release. I'm going to close this ticket since there are no more actions to be taken on my part. However, if you find that the next release does not fix this issue then please re-open this ticket and we'll investigate. Unfortunately, I do not have an ETA for the next release.

Note to Googlers: b/174146134 is the internal ticket filed for the issue. The fix is cl/344844086.
