[Ben8t]

Describe the issue

The switch value should be a list of task, not raw YAML

id: dunlin_655888
namespace: qa

tasks:
  - id: switch
    type: io.kestra.plugin.core.flow.Switch
    value: "FIRST"
    cases:
      FIRST:
        - id: first
          type: io.kestra.plugin.core.debug.Return
          format: "{{ task.id }} > {{ taskrun.startDate }}"
      SECOND:
        - id: second
          type: io.kestra.plugin.core.debug.Return
          format: "{{ task.id }} > {{ taskrun.startDate }}"
      THIRD:
        - id: third
          type: io.kestra.plugin.core.debug.Return
          format: "{{ task.id }} > {{ taskrun.startDate }}"
    defaults:
      - id: default
        type: io.kestra.plugin.core.debug.Return
        format: "{{ task.id }} > {{ taskrun.startDate }}"
