Input type parameter not passed to custom Cypher query

[johnymontana]

I've defined a custom mutation field MergeStory with a @cypher directive that takes a StoryInput. I expect the input object data to be passed to the Cypher sub-query as a parameter, however it is not included.

Partial typedefs:

type Story {
    id: ID!
    descendants: Int @cypher(statement: "")
    score: Int
    time: DateTime
    title: String
    url: String
    comments: [Comment] @relation(name: "HAS_COMMENT", direction: "OUT")
    by: User @relation(name: "SUBMITTED", direction: "IN")
}

input StoryInput {
    by: String
    id: ID!
    kids: [ID!]
    timeinput: String
    title: String
    url: String 
}

type Mutation {
    MergeStory(data: StoryInput): Story @cypher(statement: """ 
        MERGE (s:Story {id: $data.id})
        SET s.time = DateTime({formatted: $data.timeinput}),
            s.score = $data.score,
            s.title = $data.title,
            s.url   = $data.url
        MERGE (u:User {id: $data.by})
        MERGE (u)-[:SUBMITTED]->(s)
        RETURN s       
    """
    )
    
    MergeComment(data: CommentInput): Comment @cypher(statement: """
    
    )
}

Given this GraphQL query:

mutation mergeStory($data: StoryInput) {
  MergeStory(data: $data) {
    id
  }
}

{
	"data": 
    { "by": "ryan_j_naughton",
      "descendants": 0,
      "id": 19122525,
      "score": 1,
      "time": 1549723769,
      "title": "Uber\'s bike service is cutting into car rides",
       "type": "story",
      "url":
   "https://www.engadget.com/2019/02/08/uber-jump-bikes-lead-to-fewer-car-rides/" }
}

This is the generated Cypher query:

CALL apoc.cypher.doIt("MERGE (s:Story {id: $data.id})
SET s.time = DateTime({formatted: $data.timeinput}),
    s.score = $data.score,
    s.title = $data.title,
    s.url   = $data.url
MERGE (u:User {id: $data.by})
MERGE (u)-[:SUBMITTED]->(s)
RETURN s       ", {first:$first, offset:$offset}) YIELD value
    WITH apoc.map.values(value, [keys(value)[0]])[0] AS `story`
    RETURN `story` { .id } AS `story` SKIP $offset
{ first: -1, offset: 0 }

Expect data object argument to be included in apoc.cypher.doIt call, but only first and offset are included.

If I flatten the MergeStory mutation params (no input type) then it works as expected:

MergeStoryFlat(by: String, id: ID!, kids: [ID!], timeinput: String, title: String, url: String): Story @cypher(statement: """
    MERGE (s:Story {id: $id})
        SET 
            s.title = $title,
            s.url   = $url
        MERGE (u:User {id: $by})
        MERGE (u)-[:SUBMITTED]->(s)
        RETURN s     
    """

results in:

CALL apoc.cypher.doIt("MERGE (s:Story {id: $id})
    SET 
        s.title = $title,
        s.url   = $url
    MERGE (u:User {id: $by})
    MERGE (u)-[:SUBMITTED]->(s)
    RETURN s     ", {by:$by, id:$id, title:$title, url:$url, first:$first, offset:$offset}) YIELD value
    WITH apoc.map.values(value, [keys(value)[0]])[0] AS `story`
    RETURN `story` { .id } AS `story` SKIP $offset
{ by: 'ryan_j_naughton',
  id: '19122525',
  title: 'Ubers bike service is cutting into car rides',
  url:
   'https://www.engadget.com/2019/02/08/uber-jump-bikes-lead-to-fewer-car-rides/',
  first: -1,
  offset: 0 }
