Cannot update document by index in FaunaDB

Question

I'm attempting to update a document using an index in my FaunaDB collection using FQL.

Update(
  Match(
    Index('users_by_id'),
    'user-1'
  ),
  {
    data: {
      name: 'John'
    }
  }
)

This query gives me the following error:

Error: [
  {
    "position": [
      "update"
    ],
    "code": "invalid argument",
    "description": "Ref expected, Set provided."
  }
]

How can I update the document using the index users_by_id?
