[Question] GetFileAsync fails on iOS with unknown error

Please fill in the following fields:

• Unity editor version: 2022.1.8f1
• Firebase Unity SDK version: 8.10.1
• Source you installed the SDK: .tgz from https://developers.google.com/unity/archive#play_asset_delivery
• Problematic Firebase Component: storage
• Other Firebase Components in use: analytics, app, auth, crashlytics, dynamic-links, firestore, functions, remote-config
• Additional SDKs you are using: Facebook
• Platform you are using the Unity editor on: Windows
• Platform you are targeting: iOS
• Scripting Runtime: IL2CPP

Please describe the issue here:

We are trying to load file from Firebase storage using code:

var storageReference = storage.GetReferenceFromUrl(url)
storageReference .GetFileAsync()

We are using the same code on Windows, Android without any problems. On iOS, however, the same logic fails with error: An unknown error occurred, error code: 13000, httpResultCode: 300 The exception is not the informative in that case.

Any ideas why this is happening only on iOS, and what we can do to fix that issue?

The issue still persists, but we just stopped using GetFileAsync, and instead, we use GetDownloadUrlAsync to fetch url, and then manually download the file to Application.persistentDataPath via UnityWebRequest

Thanks for the additional input, @aixaCode. I was able to reproduce the issue, and it seems odd that this is encountered on just the iOS platform. I’ll let the team know about this, and you may refer to this thread for any updates.
