Are Dictionary data types supported?

[BTippen]

Having trouble saving a Dictionary. Getting this message:

NotSupportedException: ES3Type.type is null when trying to create an ES3Type for System.Collections.Generic.Dictionary`2[UnityEngine.Vector3Int,AntColony], possibly because the element type is not supported.
