Skaffold: missing resource metadata on Redis in Kubernetes

Question

I am using skaffold for my kubernetes local cluster deployment. Currently, I am trying to setup Redis. So far, I have written a "token-redis.yaml" file that contains the configmap, pvc, pv, statefulset and clusterip service. When I save the changes, skaffold gives me the following error:

"Skipping render due to error:missing Resource metadata"

This is my YAML file:

apiVersion: v1
kind: ConfigMap
metadata:
  name: token-redis-configmap
data:
  update-node.sh: |
    #!/bin/sh
    REDIS_NODES="/data/nodes.conf"
    sed -i -e "/myself/ s/[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}/${POD_IP}/" ${REDIS_NODES}
    exec "$@"
  redis.conf: |+
    cluster-enabled yes
    cluster-require-full-coverage no
    cluster-node-timeout 15000
    cluster-config-file /data/nodes.conf
    cluster-migration-barrier 1
    appendonly yes
