FIRMessagingTokenFetchOperation went isFinished=YES without being started by the queue it is in

Open p16r opened this issue 1 year ago • 5 comments

Description

Title is the error I get in the console when I try to log in in my app. I do not have the steps to replicate this 100%, but the most reliable way I have been able to replicate this is when updating my app from an older build (e.g. from TestFlight) to a newer one.

Reproducing the issue


//  This function causes a crash when FirebaseApp.app()?.delete is called.
private func setupFirebase(completion: @escaping () -> Void) {
    let filePath = /* dynamic file path based on scheme */
    let fileopts = FirebaseOptions(contentsOfFile: filePath)!

    if FirebaseApp.app() != nil {
        FirebaseApp.app()?.delete { _ in
            DispatchQueue.main.async {
                FirebaseApp.configure(options: fileopts)
                completion()
            }
        }
    } else {
        FirebaseApp.configure(options: fileopts)
        completion()
    }
}

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

google-oss-bot avatar Nov 10 '22 16:11 google-oss-bot

FYI I cannot update Xcode or Firebase version till 2023 so that is not an option for now.

Thanks for reporting, @p16r. I tried to reproduce the issue but I wasn't able to get the same error. Could you clarify on what you mean by "I have been able to replicate this is when updating my app from an older build (e.g. from TestFlight) to a newer one."? Does it mean you're updating your app itself or the SDK version? Also, did you make any changes in your code that might be the possible cause the issue?

rizafran avatar Nov 11 '22 19:11 rizafran

Thanks for helping me with this! I mean the most reliable method to replicate this crash is by updating the app from a previous build e.g. 2.10.4 build 299 to 2.10.4 build 300. i.e. I download 2.10.4-299 from TestFlight and use it on my phone, then download 2.10.4-300, and when I first run the new build, it will crash. But next run onwards it won't. I'm not changing any of the Firebase-related code in between builds. Neither is the SDK version changing between builds.

Hey, just wanted to give an update on this issue. I was able to avoid this crash by replacing existing completion-based API calls with async/await calls. Thanks for helping me out with this issue!
