GraphQL schema query problem

Hi, I am working with parts of the GRANDStack starter project (but changing it a bit for my own project). An issue is that I only get an empty array out of the following query and data:

GraphQL:

query  { Company 
  {
  name
  person {
    firstName

And the schema looks like this:

type Person {
  id: ID!
  name: String
  firstName:String
  lastName:String
  company: Company @relation(name:"position", direction:IN)
}

type Company {
  id: ID!
  name: String
  person: [Person] @relation(name:"position", direction:IN)
  }

I am using CSV data from Linkedin so the results we are getting from the GraphQL query above looks like this:

{
  "data": {
    "Company": [
      {
        "name": "ABBA THE MUSEUM",
        "person": []
      },
      {
        "name": "ZAPLIFY",
        "person": []
      },
      {
        "name": "EVERYTIME FITNESS",
        "person": []
      }

I haven't touched GraphQL yet, but....
Is it possibly that the direction for the relation is IN both as person and as company?
