On Demand Resources downloads data but can't access to it.

Hi everyone!

I'm having some problems converting my project from WWW to OnDemandResources requests for loading bundles. I was using Unity 5.5.4.p5 and I've tried Unity 2018.1 without success.

I've tried the demo assetbundlemanager (https://bitbucket.org/Unity-Technologies/assetbundledemo) but didn't work either (loads resources in xcode correctly and www server works, but it won't work in ODR mode in Testflight).

I tried using a CollectResources load like the example, and it correctly loads UnityData, but GetResourcePath returns null for every file I'm trying to retrieve. The resource names doesn't feature extensions here.

I've also tried to manually load the files into XCode, setup the OnDemand tags and retrieve files from inside there, without success too. This code is from this version.

The code will download the ondemandresources tag, fills up to 100% done without errors. Then trows and error because the odr:// doesn't exist.

This is the error:

 Request result file: 01.bundle odr://01
 UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[])
 UnityEngine.Logger:Log(LogType, Object)
 UnityEngine.Debug:Log(Object)

 ODR temp File: :

 (Filename: /Users/builduser/buildslave/unity/build/Runtime/Export/Debug.bindings.h Line: 43)
 
 UnauthorizedAccessException: Access to the path "auto/" is denied.

Do you have any ideas about how to fix this?

This Debug.Log("ODR temp File: " + request.GetResourcePath(bundleResources[iFile].Replace(".bundle",""))); outputs no output file.

I can't use www anymore, and ondemandresources is my only alternative for this project, so I would like to know how to fix this issue.

Thanks everyone!
