SerializationAbortException: Data layout mismatch

[Jérémy Guéry]

What happened?

When I try to duplicate a specific ScriptableObject with specifics serialized classes a serialization error appears.

How can we reproduce it?

• Download and open the project in attachment with Unity 2017.1.0p3
• Import Odin Inspector 1.0.6.9
• Setup a "Skill" Scriptable Object like the picture in attachment (add a SkillBehaviourOwnerBuffable and add a BuffDenfensiveMatrix in the Buffs list)
• Try to duplicate the ScriptableObject with Ctrl-D
• See the error in the console

I think the property "private Guid targetGuid;" in BuffDefensiveMatrix is causing the error. When I remove that property there is no issue anymore.

Thanks!

[Tor Esa Vestergaard]

Thanks for the report - I'll check this out and let you know what I discover.

My team is hitting the same issue, but it's only happening for us on iOS builds. If there's been any update to this issue, I'd be glad to hear it!

For reference, we're on Unity 2018.2.0f2 Odin Inspector 1.0.6.9 Editor Only mode is off

[Joel Clark]

Still debugging this issue, as it's blocking our iOS builds entirely. From what I've found, this issue happens specifically on Dictionaries on SerializedScriptableObjects (more specifically on dictionaries of string to any class). We've run the AOT Generation, the Dictionaries appear in the list of supported types, and we generate the DLL, but this error causes the build to crash on startup. Here's the full error we're getting, for reference.

Sorry I haven't been more active on this issue of late - we've been swamped with the impending release of Odin 2.0 and it simply passed me by. Thanks for sticking with it!

This is a very difficult error to debug, and I've not yet managed to reproduce it reliably on my own hardware. It seems a strange sort of error, if it only happens on iOS but is related to faults in the binary data layout. There is also the fact that certain aspects of the serialization code has changed and become more reliable in Odin 2.0. We will very likely be submitting 2.0 to the Asset Store tomorrow, and you can try it out then to see whether the issue is fixed there. I can also send you an RC build faster than that, if you mail me your Odin invoice ID at [e-mail].

If it is not fixed in 2.0, I will create a diagnostic build that does a lot of extra logging during deserialization and send it to you for testing, and we can work from that point.

[Tor Esa Vestergaard]

Does this still happen in 2.0?

[Joel Clark]

We haven't had an opportunity to update & check. We started seeing a separate issue within Unity that blocked us from testing this one. We've just cleared that one up, though, and we'll be able to try it out against 2.0 this week.

[Joel Clark]

Sorry for the delay -- we finally got a chance to test this, and 2.0 fixed the issue. Thanks!

[Tor Esa Vestergaard]

Great, I'll mark it as resolved, then - thanks for the heads-up!
