Updating Kubernetes 'default' Service Account with TF

Hello, I’m trying to update the ‘default’ service account in kubernetes that’s always created during the creation of a namespace, but unfortunately i get the error that’s reported by another https://github.com/terraform-providers/terraform-provider-kubernetes/issues/302 where i’m not sure a solution has been provided.

In short all i’m trying to do is update the service account with some annotations - can someone shed some light.
