[Feature] why this workflowrun demo failed.

[Growing111]

I use this demo
https://github.com/kubevela/workflow/blob/main/examples/workflow-run/apply-applications.yaml

yaml is

apiVersion: core.oam.dev/v1alpha1
kind: WorkflowRun
metadata:
  name: apply-applications
  namespace: default
  annotations:
    workflowrun.oam.dev/debug: "true"
spec:
  workflowSpec:
    steps:
      - name: apply-app2
        type: apply-app
        properties:
          ref:
            name: my-app
            key: application
            type: configMap
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: my-app
  namespace: default
data:
  application: |
    apiVersion: core.oam.dev/v1beta1
    kind: Application
    metadata:
      name: webservice-app2
    spec:
      components:
        - name: express-server2
          type: webservice
          properties:
            image: crccheck/hello-world
            ports:
              - port: 8000

kubevela version : v1.8.1
workflow version: v0.5.0

result:

the workflowrun status is failed

error message :

 run step(provider=kube,do=apply): the body of the request was in an unknown format - accepted media types include: application/json-patch+json, application/merge-patch+json, application/apply-patch+yaml

but webservice-app2 application is running and have a pod express-server2-58f7474c55-txqxk is runing

the next ,The yaml file I use under configMap is in another namespace test

apiVersion: core.oam.dev/v1beta1
kind: Application
metadata:
  name: webservice-app2
  namespace: test
spec:
  components:
    - name: express-server2
      type: webservice
      properties:
        image: crccheck/hello-world
        ports:
          - port: 8000

the application in namespace test is successed and running ,

why apply-applications workflowrun prompt messaget is unknown format and status is failed
