[Bug] Crash On Firebase Storage

[henry-dreamo]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2020.3.16f1
• Firebase Unity SDK version: 8.6.2
• Source you installed the SDK: .unitypackage
• Problematic Firebase Component: Storage
• Other Firebase Components in use: Auth, Functions, FireStore, Analytics, Crashlytics, Installations
• Additional SDKs you are using: Facebook, AdMob
• Platform you are using the Unity editor on: Mac(M1)
• Platform you are targeting: Android
• Scripting Runtime: IL2CPP

[REQUIRED] Please describe the issue here:

I am analyzing the logs by accumulating them in Firebase storage.
I don't know exactly how to reproduce it. Occurs intermittently when sending logs to storage.

Previously I was using StorageReference.PutBytesAsync , and I saw someone answer that PutFileAsync is better than PutFileAsync . So I've changed it now and it's still crashing intermittently.

Attempts to send logs to storage are being made only once at a time. The logic to start the transfer by reading the file starts in the created thread, but the response is always executed in the Unity main thread.
I also saw an article stating that the progress monitor problem in this GitHub issue was supposed to be corrected, but it didn't work.

I create and attach a sample project in the same process as I send logs. However, I couldn't find a way to reproduce the original project or the sample project.

My test Android device crashed once on a weak network. It occurred when I continued the app after turning on the phone for a long time. But I'm still not sure if the crash is the same as this crash.

When using Firebase 8.2.0, the log sender crash came out as follows.

Currently, I have updated to Firebase 8.6.2, and the crashes below are occurring more often than the crashes seen before.
(Physics from the crash stack are not used.)

Steps to reproduce:

There is no clear way to reproduce it.
There are cases where the gzip file was sent as a log several times from a weak network and crashed.

Relevant Code:

// TODO(you): code here to reproduce the problem

SampleProject

https://github.com/dream-o/FirebaseCrashSample

I created a sample Firebase project and a sample Unity project and configured it with my current project version, 8.6.2.
The log sending method is configured in the same way as the one I currently send.

Thanks for reporting this, @henry-dreamo. While I try to replicate this, could you confirm if the issue persists using the latest version of the SDK (8.7.0)?

[henry-dreamo]

@paulinon
okay.
I'll try to apply 8.7.0 to the update in two weeks.

Hey @henry-dreamo. 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!

We plan to update by applying 8.7.0 next week.
Have you ever found anything?
