wrong (this) parameter value for cypher directive on relationship

[ikwattro]

Given the following schema :

type Role @relation(name:"ACTED_IN", from:"actor", to:"movie") {
   actor: Person
   movie: Movie
   roles: [String]
   type: String @cypher(statement:"""
     RETURN type(this)
     """)
}

type Person {
  name: String
  born: Int
  roles: [Role]
  _all: String
  _id: ID!
}

type Movie {
  title: String
  released: Int
  characters: [Role]
  _all: String
  _id: ID!
  _labels: [String] @cypher(statement:"""
  RETURN labels(this)
  """)
}

And the following query :

query {
  person(first: 1) {
    roles {
      type
    }
  }
}

The generated query is :

MATCH (person:Person)
RETURN person {
	roles: [(person)-[personRoles:ACTED_IN]->(personRolesMovie:Movie) | personRoles {
		type: apoc.cypher.runFirstColumnSingle('WITH $this AS this RETURN type(this)',  {
			this: personRolesMovie
		})
	}]
} AS person LIMIT $personFirst

The parameter value given for this is wrong. It should be personRoles instead of personRolesMovie .
