Cloud Provider - Infrastructure Definition Issue

I have a cloud provider created for my kubernetes cluster, and when I test the connection in the Cloud Provider setup page it is successful. However, when I go to update my Infrastructure Definition on one of my Environments, it fails as soon as I hit Submit to save it.

Error message is: Invalid request: Invalid request: error: the server doesn’t have a resource type “Deployment”

I have checked the permissions for the service account in the cluster and see no problems there. Any ideas?
