I would expect something like:

    places: [
      [Object], [Object], [Object],
      [Object], [Object], [Object],
      [Object], [Object], [Object],

      [Object], [Object], [Object],
      [Object], [Object], [Object],
      [Object], [Object]
    ],
    contextualContents: [],
    nextPageToken: ''
  },
  null,
  null
]
