Kube2iam not assuming roles on kops

[craig-dsilva]

I have Kubernetes (v 1.28.4) running with Kops (v 1.28.1 previously running v1.19) on AWS. Recently we upgraded the cluster and kube2iam stopped working and is not assigning roles to the pods. I don't know what has gone wrong as it used to work with the previous version. Even the logs do not give me too much info.
