Bug Addressables - UnityWebRequest ConnectionError : Malformed URL (IOS) - Unity 2022.1.0f1

Hi, I'm getting an error loading the local addressable assets, possibly remote addressables too, but the game doesn't even start.

I'm just doing an Addressables.InitializeAsync (which succeeds), and then
Addressables.LoadAssetAsync or assetReference.LoadAssetAsync

This only happens on iOS platform. After inspecting the payloads content of the .ipa file, the file DOES exists.
On the Android platform it is working as expected.
In the Editor it works fine too, even with the Play Mode Script set to Simulate Groups or Use Exististing Build

I'm using UCB for our automated builds, haven't tried building myself yet.

This occurred after upgrading from Unity 2021.3.2f1 to 2022.1.0f1
Tried the following things, but didn't work
- Upgrading from Addressables 1.19.19 to 1.20.0. (1.19.19 worked fine on 2021.3.X builds)
- Enable/Disable "Asset Bundle CRC"
- Enable/Disable "Use UnityWebRequest for Local Asset Bundles"
- Allow downloads over HTTP "Always Allowed / Not Allowed"


The exception:

Code (CSharp):

1.  System.Exception: Dependency Exception ---> UnityEngine.ResourceManagement.Exceptions.OperationException: GroupOperation failed because one of its dependencies failed ---> UnityEngine.ResourceManagement.Exceptions.RemoteProviderException: RemoteProviderException : Unable to load asset bundle from : file:////var/containers/Bundle/Application/163FBCFA-C5DD-4615-8C94-7F5AF1EB5868/*App Game Name*.app/Data/Raw/aa/iOS/92b65e9b8b2492b47a63bb3444987431_unitybuiltinshaders_46dc4b9d65476455d9d3e76704368b23.bundle
2. UnityWebRequest result : ConnectionError : Malformed URL

I suspect that something is changed in 2022.1.X with handling URL for iOS platform, the 'malformed' url looks perfectly fine.
Any clues on how to fix this issue?

 

Just tested with 2022.1.1f1, same error still occurs only on iOS.

 

Also tested on 2022.1.2f1, same error...

 

Same at 2022.1.10f1.... And no mention about this in known issues! The problem have been there for a couple of months and you even didn't mention it in known issues? How so?

 

Same at 2022.1.10f1 .
I've just fixed this in Editor at least
Just "file:///....." -> "file://..."

so remove one "/"
Did not check it on the real diveces

 

Odd it may be another bug you're encountering,
The case, what I had only happened to me on the iOS platform.
Editor, Android, Windows platform seems to work fine.

I've submitted a bug report, and the issue is confirmed by the Unity Team, so we just have to wait for a fix.
It apparently happens if you (Player Settings->Player->Product Name) contains any space(s).

So a temporary fix is to remove any spaces in your product name, which is kinda unacceptable if your product contains spaces.

 

Had the same issue as OP with the extra / in file:////

for us on
Unity: 2021.3.1f1
Addressables: 1.19.19
Target Platform: Linux & OSX.
The same did not occur if the target platform was Windows or Android.

The WebRequest override 'fix' suggested by @pillakirsten with a simple [request.url = request.url.Replace("file:////", "file:///");] worked.

Still, no clue about why the //// for those platforms.

 

This issue has been fixed in Addressable 1.21.1

Hi,

I was asking about a similar topic here:
https://forum.unity.com/threads/addressables-not-loading-on-ios-device.805824/#post-9120865

In the meantime I updated to Addressables 1.21.1. Also I have a Product Name without spaces.
But I keep having the problem because the WebRequestOveride function is not even called and the addresses from the catalog are pointing to a non existent URI in my case. I need to read local files where the folder structure is determined at runtime. That is why I am dependent on the override function. On Android it works just fine. Any ideas?
Thanks
