In this command definition, how do I output the value of the app.kubernetes.io/component label of each object?

command: ls: {
  task: print: cli.Print & {
    text: tabwriter.Write([
      for x in objects {
        "\(x.kind)  \t\(x.metadata.labels[app.kubernetes.io/component])  \t\(x.metadata.name)"
      },
    ])
  }
}

You should use quotes here, so "app.kubernetes.io/component"
