Bug WebRequestAsyncOperation.completed lies to me on iOS?

I have a pretty straightforward Bundle Manager that loads my AssetBundles as needed. I mostly rely on the various callbacks to move individual WebRequests through their steps to completion. This works fine on Android and Win.

However, on iOS when the UnityWebRequestAsyncOperation.completed fires DownloadHandlerAssetBundle.GetContent(theWebRequest) returns the following console error:

InvalidOperationException: Cannot get content from an unfinished UnityWebRequest object.

Here is some paraphrase code to give you a more clear idea...

Code (CSharp):

1. public virtual void Load()
2.         {
3.             InitializeWebRequest(_bundlePath);
4.             BeginWebRequest();
5.         }
6.  
7.         protected void InitializeWebRequest(string path)
8.         {
9.             _webRequest = UnityWebRequestAssetBundle.GetAssetBundle(path, Hash);
10.             _bundleHandler = new DownloadHandlerAssetBundle(path, Hash, 0);
11.             _webRequest.downloadHandler = _bundleHandler;
12.         }
13.  
14.         protected void BeginWebRequest()
15.         {
16.             _bundleOperation = _webRequest.SendWebRequest();
17.             _bundleOperation.completed += WebRequestComplete;
18.         }
19.  
20.         protected virtual void WebRequestComplete(AsyncOperation op)
21.         {
22.             _bundleOperation.completed -= WebRequestComplete;
23.  
24.            //Error happens here but only on iOS...
25.             _bundle = DownloadHandlerAssetBundle.GetContent(_webRequest);
26.             if (_bundle != null)
27.             {
28.                 _bundleRequest = _bundle.LoadAllAssetsAsync();
29.                 _bundleRequest.completed += LoadCompleteInternal;
30.             }
31.         }

Any ideas?

 

Only if you promise to confirm this one in less than 2 months.

 

Lol, I know. It's been reported! Hopefully its just something I'm doing.
