Ordering of sorting criteria not honoured in vector search query

[darrellwarde]

Type definitions

type Movie
  @vector(
    indexes: [
      {
        indexName: "MovieIndex"
        embeddingProperty: "embedding"
        queryName: "searchMovies"
      }
    ]
  )
  @node {
  title: String!
  released: Int!
}

Steps to reproduce

The generated Cypher of the following query sorts by score first, as indicated by the array index in the sort argument.

query ($vector: [Float!]) {
  searchMovies(
    vector: $vector
    sort: [{ score: ASC }, { node: { title: DESC } }]
  ) {
    edges {
      score
      node {
        title
      }
    }
  }
}

This query should sort by title first, but it does not - the generated Cypher is identical to above and the results are identical:

query ($vector: [Float!]) {
  searchMovies(
    vector: $vector
    sort: [{ node: { title: DESC } }, { score: ASC }]
  ) {
    edges {
      score
      node {
        title
      }
    }
  }
}
