Description

trying to modify a subcategory element to be a top-level category, but it's not working.
tried parentId value of null, -1, and 0.
Moving from a subcategory to another subcategory works fine
Moving to the top level is not working.
I'm confused if it's a bug or tried that doesn't work by default in wp-graphql.

Steps to reproduce

mutation updateCaegory($id: ID!, $parentId: ID) {
  updateCategory(input: {id: $id, parentId: $parentId, clientMutationId: "34343"}) {
    category {
      id
      databaseId
      parentDatabaseId
      name
      parentId
    }
    clientMutationId
  }
}

{
"id":37,
"parentId":0
}

{
"id":37,
"parentId": null
}

{
"id":37,
"parentId": -1
}
