UnityEngine.AddressableAssets.InvalidKeyException

Hi,

I have recently begun using addressables in my project, in order to reduce RAM usage (I am storing references to a lot of game objects in the editor).

Everything is working fine, but I am intermittently getting the above error. This is my code:

Code (CSharp):

1.                    
2.  if (cs.contentADD[i] != null)
3.                     {
4.                         var go = cs.contentADD[i].InstantiateAsync();
5.                         while (!go.IsDone)
6.                             yield return new WaitForSeconds(0.1f);
7.                     }
8.  

I am getting the above error on the line with instantiateasync().

I have tried deleting the addressables and rebuilding the library, selecting and deselecting the addressables, etc, etc, and nothing seems to work.

Everything works fine when I load these objects as prefabs, and everything looks fine in the editor, etc.

I am calling the above code in a coroutine, is it possible that there is some kind of issue where two instantiateasyncs run at the same time?

That doesn't seem to be the case from what I can see though.

Any ideas?

Thanks!
