vector.dev sample json

config.yaml

api:
  enabled: true
data_dir: /tmp/vector-data-dir
sources:
  demo:
    type: "demo_logs"
    format: "json"
    interval: 2.0
transforms:
  parse_demo:
    type: remap
    inputs:
      - demo
    source: |-
      .foo = "bar"
sinks:
  stdout:
    type: console
    inputs:
      - parse_demo
    encoding:
      codec: text

Changing the sink.stdout.encoding: json resolved my confusion around this.
