Curvy does not like Unity 2021.3 (Attribute Conflicts)

[KasimirBlust]

Hi,
I just upgraded to the new Curvy Splines 8 from 7, because it didn't seem to work anymore.
Sadly the same problem persists in the new version 8 as you can see from the errors I get adding it.

Using Unity 2021.3.16f LTS.

I have a lot of conflicts with Attributes like NotNull. Unity probably added those attributes in the recent Unity version? If you could fix these by specifying the Jetbrains attributes directly, that would be nice

Hi
I used various Unity 2021.3.X versions with Curvy and I never had this issue. The latest one I used is 20221.3.17. I will try 2021.3.16 tomorrow (it is night here right now). Will keep you updated. In case this version works too for me (which I am expecting), can you please prepare a reproduction case?
Thanks

Hi
Tested with 2021.3.16f LTS and it works fine. Looked in Unity's APi for UnityEngine.NotNullAttribute, and it does not exist. Problem is probably triggered by some package you use. Can you pinpoint please what triggers the issue? Also, can you update the title to reflect that the issue is with that specific package, instead of whole Unity 2021.3, to avoid giving the impression that the asset is not maintained to new comers/by passers.
Thanks and have a nice day
