[Bug] Firebase 11.1 causing multiple issues

[brenofurlanpixo]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2021.3.14f1
• Firebase Unity SDK version: 11.1.0
• Source you installed the SDK: UPM
• Problematic Firebase Component: Crashlytics, Core
• Other Firebase Components in use: Auth, Firestore, Storage, Messaging, Installation, Auth, Remote Config, Analytics
• Additional SDKs you are using: iron-source
• Platform you are using the Unity editor on: mac, windows and linux
• Platform you are targeting: iOS and Android
• Scripting Runtime: IL2CPP
• Pre-built SDK from the website or open-source from this repo: Website

[REQUIRED] Please describe the issue here:

Since we'd updated the Firebase SDK to 11.0+ we've found several issues across our project:

Editor - NOT FIXED

After updating we are occasionally experiencing Editor crashes that are linked to the Firebase SDK. We haven't been able to specifically identify where, although I'm going to provide some logs as it may be useful:

	Managed Stacktrace:
=================================================================

	  at UnityEngine.SceneManagement.SceneManager:Internal_SceneLoaded <0x00052>
	  at <Module>:runtime_invoke_void_Scene_int <0x00098

This only happens when trying to connect with Firebase services, there's also this other log:

FunctionsException: INTERNAL
Firebase.Functions.HttpsCallableReference.<CallAsync>b__9_0 (System.Threading.Tasks.Task`1[TResult] task) (at /home/runner/work/firebase-unity-sdk/firebase-unity-sdk/functions/src/HttpsCallableReference.cs:88)

System.Threading.Tasks.Task.Execute () (at <41229cbbc9214cf28863fc47f2e1508c>:0)
--- End of stack trace from previous location where exception was thrown ---

This happens on Editor, but you can see that we've got some logs for '/home/runner' path, perhaps this is an issue with Firebase CI?

Steps to reproduce:

It happens really occasionally, no specific steps are recorded but this issue is present in both MacOS Ventura 13.1 and Windows 11

Build - WORKAROUNDED

We found that running Android builds on Linux environments will output broken builds which cannot be opened.
This is due this error, when triggered Crashlytics can't generate the build_id property and will prevent the game from opening:

Assembly 'Packages/com.google.firebase.crashlytics/Firebase/Editor/Firebase.Crashlytics.Editor.dll' will not be loaded due to errors:

Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform?"

To solve this we had to add iOS Build Support for CI Android, which is not optimal.

If I can provide any further info or help please let me know, thanks :)

[EDIT]

Issue also present on MacOS 12.5

Hi @brenofurlanpixo,

Thanks for bringing this to our attention. For your editor, could you try if version 11.2.0 of the SDK resolves the issue? It may contain a fix for the crash you're facing. Could you also confirm if either iOS or Validate References is deselected in your Firebase.Crashlytics.Editor.dll file? This could be found in your Assets > Firebase > Editor folder.

[brenofurlanpixo]

Hey there @paulinon thanks for your reply!
I'll be updating the plugin version and will keep you updated if it solves the issue regarding the random crashes.

Also, here's the import config for the Crashlytics.Editor.dll

[brenofurlanpixo]

Hello again!
We've updated the Firebase packages to the requested version although this doesn't seems to have it fixed.
We are trying to get a insightful log, the cause itself seems to be the very same, also it is related to scene reload + firebase requests running

UnityEngine.SceneManagement.SceneManager:Internal_SceneLoaded (UnityEngine.SceneManagement.Scene,UnityEngine.SceneManagement.LoadSceneMode) (at /Users/bokken/build/output/unity/unity/Runtime/Export/SceneManager/SceneManager.cs:244)

We're now able to reproduce this error following a step-by-step action, where we try to load a JSON from the Firebase Cloud Storage while loading a Scene

[Edit] Happens constantly with scene load/unload, not entirely linked with a Firebase request or something

[brenofurlanpixo]

Further tests showed that those are not only related with Scene load:

On this action we're just opening a screen where you can check whats the current save state (i.e. synced or not) with firebase

Hi @brenofurlanpixo,

Does unticking Validate References resolve the issue related to your build? Also, could you provide a minimal, reproducible example of your implementation along with the complete steps to replicate the issue related to the editor so that we can identify what's causing the crashes?

[brenofurlanpixo]

Hey there @paulinon !

CI Issue fix Attempt

We've uploaded a modified version of crashlytics with the Validate References toggled off but it seems to not have the issue solved. Apart from not getting the build_id generated properly, it seems to have returned other errors:

TypeLoadException: Failure has occurred while loading a type.
Rethrow as TypeInitializationException: The type initializer for 'Firebase.Crashlytics.Editor.PathConstants' threw an exception.

Editor Crashes

I was investigating this very issue and found out that when calling FirebaseUser.UserId multiple times in the same session leads to this crash-ish unity editor.

We were handling it as property: public string FirebaseId => FirebaseUser?.UserId;
This were used called on some UI methods such as view.SetUserIdText(firebaseAuth.FirebaseId);
After some test and validation, we've found that:

• Caching this value prevents crashing throughout Editor where it were crashing (such as app reload, opening UI and changing scenes).
  The implementation now is something like: public string FirebaseId => cachedFirebaseID ?? FirebaseUser?.UserId;
• Upgrading the plugin from 11.1 -> 11.2 causes this to be very constant, where it crashes every single time I head to reload the game on editor
• Downgrading it to 10.7 doesnt fix this, but on 9.6 it does (downgrading isn't an option tho, we've just verifying wether version was or was not working alongside with our implementation)

We're using a very straightforward implementation of Firebase.Auth (i.e.: there isn't too much going on on-top of it after grabbing the UserID value), but if I can provide with any further info let me know :)

Hi @brenofurlanpixo,

Thanks for the update. It seems that the behavior you're facing with the build is similar to this issue in the External Dependency Manager repository. You may refer to this thread for updates.

Does the issue persist if you update your Unity editor to a later version (2022.3.4f1 is the latest LTS version)? It would be helpful if you provide a minimal, reproducible example as this could be used as a baseline for troubleshooting.

Hey @brenofurlanpixo. 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!

[brenofurlanpixo]

Hey there!
Just updating here to avoid auto-closing of this issue as it is not yet solved - we're keeping an eye on both threads
Sorry for the bit delay for providing the requested minimal example. We'll make some tests and provide it as soon as possible.
Thanks for your time :)

Since there haven't been any recent updates here, I am going to close this issue.

@brenofurlanpixo if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.

We have just updated from Firebase 10.4.0 to 11.2.0 and we're getting this Editor crash randomly, across all our editors. In our case the call stack is:

There have been no changes to our auth code, the only change has been updating Firebase while integrating Firebase Messaging. There is clearly something broken here, please re-open.
