Description

Describe your issue.
When I try to define a component and a type with a field of type Coordinates, I am able to generate the code just fine and no errors in the Unity console. But as soon as the project refreshes (by editing a script or playing the scene), in the unity console I get the error:

InvalidCastException: Specified cast is not valid.
Improbable.Gdk.Debug.MonoBehaviourInspector.OnEnable () (at Library/PackageCache/io.improbable.gdk.debug@0.4.0/MonoBehaviourInspector.cs:46)

I am able to play the scene just fine and everything works as expected.

Schema file for reference:

package player;

import "improbable/gdk/core/common.schema";
import "improbable/standard_library.schema";

type ViveTransform
{
    improbable.Coordinates position = 1;
    improbable.Coordinates rotation = 2;
}
component PlayerViveTransform 
{
    id = 22003;
    ViveTransform head = 1;
    ViveTransform left_controller = 2;
    ViveTransform right_controller =3;
}

Steps to reproduce

1. Create a schema file and define a type that has a field of type Coordinates
2. Generate the code
3. Modify any script or play the scene so that the project reloads
