Kubernetes modules fail when manifest kind is List

[padamson-r7]

Bug

Current Behavior

deploying a kubernetes module that uses List kind will throws this error:

Failed getting status for service 'spring-config-watcher' (from module 'spring-config-watcher'). Here is the output:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Cannot read property 'namespace' of undefined
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Reproducible example

kind: Project
name: temp
environments:
- name: local
  providers:
  - name: local-kubernetes
    setupIngressController: false

---
  kind: Module
  type: kubernetes
  name: spring-config-watcher
  files: [spring-config-watcher.yml]

where the manifest is of kind List:

---
apiVersion: v1
kind: List
items:
  - apiVersion: v1
    kind: Service
    metadata:
...

The full manifest I was using is here:

Workaround

refactor the List into a multi-document yaml file
