GCP Deployment Manager Delete RESOURCE_ERROR - google-cloud-platform

Question

I created a Deployment Manager Template (python) to create a GKE Zonal cluster (v1beta1 feature). When I run gcloud deployment-manager deployments create <deploymentname> --config <config.yaml>, GKE cluster is created as expected.
I used type:gcp-types/container-v1beta1:projects.zones.clusters in my python template.
However, when I run the delete command on DM i.e. gcloud deployment-manager deployments delete <deploymentname> I get the following error:
Error says that field name could not be found. However, I did specify name in my config.yaml file.
Error in Operation [operation-1536152440470-5751f5c88f9f3-5ca3a167-d12a593d]: errors:
- code: RESOURCE_ERROR

Here's the sample config.yaml
imports:
- path: templates/gke/gke.py
name: gke.py
resources:
- name: ${CLUSTER_NAME}
type: gke.py
properties:
zone: ${ZONE}
cluster:
name: ${CLUSTER_NAME}
description: test gke cluster
network: ${NETWORK_NAME}
subnetwork: ${SUBNET_NAME}
initialClusterVersion: ${CLUSTER_VERSION}
nodePools:
- name: ${NODEPOOL_NAME}
initialNodeCount: ${NODE_COUNT}
config:
machineType: ${MACHINE_TYPE}
diskSizeGb: 100

Any ideas what I'm missing here?
