[2018.3.8f1][0.6.7][Case 1138947] AAS completly broken

We somehow managed to completly break the AAS. It does not read the groups correctly and one group is missing

The none group is the Prefabs.asset group

Which is completly broken and does not show an inspector

P4 merge does not show any difference to the file on the PC where it is broken

to the PC where it works

These are the errors the AAS reports

Code (CSharp):

1. [Exception] NullReferenceException: Object reference not set to an instance of an object
2. AddressableAssetSettings.IsNotUniqueGroupName()    Library/PackageCache/com.unity.addressables@0.6.7-preview/Editor/Settings/AddressableAssetSettings.cs:1214
3.  
4. AddressableAssetSettings.FindUniqueGroupName()    Library/PackageCache/com.unity.addressables@0.6.7-preview/Editor/Settings/AddressableAssetSettings.cs:1198

Okay that one was scary. Not even deleting /Library and /Obj helped to restore this. Neither copying the whole AAS folder into the project from a station where it worked helped - likely because the .meta and ids did not match.

Only recreating all settings helped.

 

The deserialization fails and that seems to be the problem in this project.

Code (CSharp):

1. [Exception] ArgumentException: Object at index 0 is null
2. UnityEditor.SerializedObject..ctor()    C:/buildslave/unity/build/Editor/Mono/SerializedObject.bindings.cs:23
3.  
4. AddressableAssetGroupSchema.OnGUI()    Library/PackageCache/com.unity.addressables@0.6.7-preview/Editor/Settings/AddressableAssetGroupSchema.cs:50
5. 48:   {
6. 49:       var type = GetType();
7. -->50:       var so = new SerializedObject(this);
8. 51:       var p = so.GetIterator();
9. 52:       p.Next(true);
10.  
11. AddressableAssetGroupInspector.OnInspectorGUI()    Library/PackageCache/com.unity.addressables@0.6.7-preview/Editor/GUI/AddressableAssetGroupInspector.cs:103
12. 101:   try
13. 102:   {
14. -->103:       schema.OnGUI();
15. 104:   }
16. 105:   catch (Exception se)
17.  
18. GUIUtility.ProcessEvent()
19.  

And it creates a whole bunch of new assets


And this gif shows how the Default Local Group is broken and cannot be serialized/deserialized correctly

 

Hey @MNNoxMortem - really sorry to see this happening. Looks like a weird upgrade issue. Were you going form 0.5.3 up to 0.6.7? or from something older?

@unity_bill Can happen The big problem just was that this was infectious. We recreated the settings, committed the changes and when the next person pulled it - bam

Also I should note that this was not during the update progress but later. So we were already using 0.6.7 successfully for some time, but as it was still timely close enough to the usage of 0.5.3 this might be related to switching branches between 0.5.3 and 0.6.7 and from my experience with unity stuff likey this (usually more when those branches do not share the platform or unity editor version) sometimes can still lead to some problems with de/serialization. However, this is just an uneducated guess, but I try to provide all information which comes to my mind.

Yes we were upgrading form 0.5.3 to 0.6.7 and at the moment it works. Even on the station where it broke initially he does not see any group labels (just empty) but everything else seems to work again after creating everything new.
