Use Addressables API to load sprite in Resources : failed

version 0.4.8

I have a single sprite texture in Resources: Assets/Resources/Image.png
It's not Addressable

When I load like this: Resources.Load<Sprite>("Assets/Resources/Image"), it's OK.

But when I load like this: Addressables.LoadAsset<Sprite>("Assets/Resources/Image").Completed+=call back func
In call back func,obj.Status = AsyncOperationStatus.Failed

 

I tried this, and it's ok:
Addressables.LoadAsset<Texture2D>("Assets/Resources/Image")

 

I found the code in LegacyResourcesProvider.cs
:

Code (CSharp):

1. public InternalProviderOperation<TObject> StartOp(IResourceLocation location)
2.             {
3.                 m_result = null;
4.                 m_requestOperation = Resources.LoadAsync<Object>(location.InternalId);
5.                 if (m_requestOperation.isDone)
6.                     DelayedActionManager.AddAction((System.Action<AsyncOperation>)OnComplete, 0, m_requestOperation);
7.                 else
8.                     m_requestOperation.completed += OnComplete;
9.                 return base.Start(location);
10.             }

It Load Object, then convert to TObject. This means it will load the default type of asset....
