[GraphQL] relatedTo variable type [Int] and [QueryArgument] conflict

[samput]

Description

Querying an entry by ID requires that the variable type be [QueryArgument]. However related entries require the variable type to be [Int]

Query variable

{
  "id": 173
}

Query [QueryArgument]

query Series($id: [QueryArgument]) {
  entry(section: "series", id: $id) {
    id
    title
  }
  pipeline: entries(section:"pipeline", type: ["ongoing", "monthly"], relatedTo: $id) {
    id
    title
  }
}

Error [QueryArgument]

{
  "errors": [
    {
      "message": "Variable \"$id\" of type \"[QueryArgument]\" used in position expecting type \"[Int]\".",
      "category": "graphql",
      "locations": [
        {
          "line": 1,
          "column": 14
        },
        {
          "line": 6,
          "column": 82
        }
      ]
    }
  ]
}

Query [Int]

query Series($id: [Int]) {
  entry(section: "series", id: $id) {
    id
    title
  }
  pipeline: entries(section:"pipeline", type: ["ongoing", "monthly"], relatedTo: $id) {
    id
    title
  }
}

Error [Int]

{
  "errors": [
    {
      "message": "Variable \"$id\" of type \"[Int]\" used in position expecting type \"[QueryArgument]\".",
      "category": "graphql",
      "locations": [
        {
          "line": 1,
          "column": 14
        },
        {
          "line": 2,
          "column": 32
        }
      ]
    }
  ]
}

Yes, that's correct. This is because the id can be in the form of ["not", 1, 2, 3] while the relatedTo accepts only ids of elements that must be related.

If you know the field the relationship is used on, you can, however, use that field as the argument instead of using relatedTo, and that should also be expecting an array of QueryArgument values.

@andris-sevcenko ah ok that makes sense. Using the field as an argument works perfectly. Thanks for the help!

Can we have an example maybe in the docs. I'm having a similar issue and can't find a good solution / explanation.
For example i'm trying to do this.

query($id: [Int!], $entryID: [Int!]) {
    entries(section: "items", relatedTo: $id, id: ["not", $entryID]) {
    ...

[mediabeastnz]

Never mind... figured it out 🤦‍♂️

I've now got ...

query($id: [Int!], $entryID: QueryArgument) {
    entries(section: "items", relatedTo: $id, id: ["not", $entryID]) {
    ...

[andris-sevcenko]

@mediabeastnz glad you figured it out! I agree that there are some murky things we should clear up in GraphQL. I'll see how soon we can fill those gaps.

[nomi-invozone]

query($id: ID!, $entryID: QueryArgument) {
entries(section: "items", relatedTo: $id, id:$entryID) {
...

well like this also works for me
