firebase-unity-sdk: [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.

Good moorning. We faced quite same issue, but with function GetBytesAsync:

we use Firebase.Storage to store some raw binary files. By a twist of fate I have the same account for login with test email through UnityEditor (win/mac) and through Apple Login on my IPhone.

We use PutBytesAsync to upload data on storage. And it works on every (Editor win/mac, win Builds (il2cpp), Android builds (il2cpp), and iOS also) platform on the same way (as a ressult, we handle the same file on Storage’s bucket: I Load it by hand from web-page and view from byte-viewer programm).

But when we call GetBytesAsync we receive byte-array of the same length, but iOS download it with another content.

Unfortunatly, I’ll be able to provide enhanced information this evening (about 8PM, UTC +3). But I believe that GetFileAsync failed on the same reason: in some way iOS load byte-data in an inappropriate way.

At this evening I’'ll provide both byte-array data that has been uploaded and that has been downloaded.

P.S.: we use very old version of SDK (8.2), but as I can see update version wasn’t helpful for other colleagues. I’ll update it to the latest version this night and report you about results next morning (UTC+3) this time.

But you may have some thoughts about it before my sdk-upgrade event, I’ll glad to test them. Thanx a lot!
