Field-level cypher statements do not work when accepting parameters in Apollo-server

Question

The cypher directive on a field-level does not work as expected.

Minimal example:

type Question {
  id: ID! @id
  required: Boolean
  testing(someId: ID!): Boolean
    @cypher(statement: """
      MATCH (q:Question {id:$someId}) RETURN q.required
    """)
}

When running the below query, I'm getting an error.

{
  Question {
    testing(someId: "12345678-1234-1234-1234-0123456789ab")
  }
}

This is the error log as seen in the Apollo Playground:

My package.json includes these versions:

"apollo-server": "^2.25.0",
"apollo-server-core": "^2.25.0",
"graphql-tag": "^2.12.5",
"neo4j-driver": "^4.3.1",
"neo4j-graphql-js": "^2.19.2",

Top-level queries (with arguments) and field-level queries with the cypher decorator work fine as long as these do not accept parameters. I was under the impression that this has worked earlier.

The library "neo4j-graphql-js": "^2.19.2" does not seem to pass on custom parameters unless you create a mutation. Try the following way:

type Question {
  id: ID! @id
  required: Boolean
}

extend type Mutation {
  testing(someId: ID!): Boolean
    @cypher(
      statement: """
      MATCH (q:Question {id: $someId}) RETURN q.required
      """
    )
}

mutation {
  testing (someId: "12345678-1234-1234-1234-0123456789ab") 
}
