Localization : SerializeReference multiple errors on fresh download

Hi all,
I would like to try the Localization package as it might be just what I need for a project. I installed it by adding the dependency in the manifest file with the line

"com.unity.localization": "0.7.1-preview"

but as soon as it downloads I get the following errors:

-----CompilerOutput:-stderr----------
-----EndCompilerOutput---------------

I’m using Unity 2019.2

Any pointers?
Thanks!

Sorry the package only supports 2019.3 and above. This is because the Serialisereference feature is only available on 2019.3 and above :wink:
