Why using the count function in neo4j with graphql returns two values ​called low and high?

Question

If I execute the following cypher in Neo4j browser returns the expected values

MATCH (n:Document)
RETURN { 
    year: n.year ,
    countdocs : COUNT(n) 
}

Result:

{"countdocs":3,"year":"2018"}    

But If I execute the same cypher in neo4j-graphql

type Query {
    totalActivityOverTime: [JSONObject] @cypher(statement: """
       MATCH (n:Document)
        RETURN { 
         year: n.year ,
         countdocs : COUNT(n) 
       }
    """) 
}

returns :

  {
    "countdocs": {
      "low": 3,
      "high": 0
    },
    "year": "2018"
  },

What means the values ​​low and high?

Thanks!

Thanks to @Sbunzini and @stdob-- I found the solution:

Schema:

type Activity{
  year: String
  countdocs: Int
}

type Query {
    totalActivityOverTime: [Activity] @cypher(statement: """
       MATCH (n:Document)
        RETURN { 
         year: n.year ,
         countdocs : COUNT(n) 
       }
    """) 
}

GraphQL:

{
  totalActivityOverTime{
    year
    countdocs 
  }
}

Thanks!
