Exception when analyzing Unity 6 asset bundles

[lukechatton]

After upgrading to Unity 6, I'm seeing this error when using the analyze command on an asset bundle.

Device Info:

• Mac
• Unity 6 (6000.0.37f1)

Command:

UnityDataTool analyze ./ -o ~/Desktop/bundles.db

Error:

System.Exception: Unsupported ManagedReferenceRegistry version 1001

So further investigating this - seems to be related to using [SerializeReference]. (which makes sense since this is the reference registry)

Having a non-null value, we instead get a different number:

System.Exception: Unsupported ManagedReferenceRegistry version 2029256710

Would it be likely that there's some change with Unity 6 here, with the binary format?

Thanks @lukechatton and @Vorlias for logging this.

I hit the same "Unsupported ManagedReferenceRegistry version 1001" issue when looking at output of building the (megacity)[https://github.com/Unity-Technologies/megacity-metro] example.

I didn't test different versions of Unity to confirm your statement that it appeared to be a Unity 6 issue. From my understanding it seemed to be more about SerializeReference classes that themselves have SerializeReference fields on them (e.g. a nesting situation).

I'm pushed up a fix 0f33e5c, I think that will clear up the problem for you.
