VR/AR Toolkit issue

Question

I tried to create the Hello World example but when I play the scene I get the following error:

AsyncRequestCompleted The remote server returned an error: (422) Unprocessable Entity. UnityEngine.Debug:Log(Object) Autodesk.Forge.ARKit.RequestQueueMgr:AsyncRequestCompleted(Object, AsyncCompletedEventArgs) (at Assets/Forge/CodeBase/RequestQueue.cs:322) UnityEngine.UnitySynchronizationContext:ExecuteTasks()

The game scene then just displays as black. Any ideas? I'm using the latest toolkit (Nov 2018).

Cheers, Chris

Answer 1

There was an issue in the new version of the toolkit where certain web requests to the server would contain an unsupported HTTP header, ending with a 422 error code. On Wednesday, Jan 9, around 5:00PM CET, we deployed a fix to the production servers which addresses the issue. If you're still seeing the issue, please send us an email to forge [dot] help [at] autodesk [dot] com with details (urn, time of the request, etc.) and we'll get back to you.
