Not compatible with multi-scene setup [0.1.2]

I'm unable to run the asset completely, in the multi-scene setup. This is on Fast / Virtual.
When I just press play I get following error:

Code (CSharp):

1. ArgumentException: An element with the same key already exists in the dictionary.
2. System.Collections.Generic.Dictionary`2[System.Object,UnityEngine.AddressableAssets.ContentCatalogData+DataEntry].Add (System.Object key, UnityEngine.AddressableAssets.DataEntry value) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:404)

@audrey-unity Any ETA on multi-scene support? I'd really like to use Addressables, they're invaluable for my project.

 

Not really. I've rolled back the changes quite some time ago, but as far as I remember, there was like only one group.
I haven't changed much in terms of default settings of asset bundling.

My wild guess on what's going on is that assets have pushed multiple times to the dictionary for some reason when there's multiple scenes loaded.

Why not just assign values to the keys ignoring checks? Like:
Dictionary[key] = Value;

It would update existing keys, and get rid of the errors as well.
As for the extra checks, they could be performed inside conditional method.
Warning should be sufficient, unless there's some reason behind not assigning possible duplicates.

 

Should it be available now ?

I'm still on 0.1.2-preview and I have the same exceptions and stacktraces

 

Seems to work here
