GraphQL error: Unknown argument 'deleted' on field 'removeFromPostsOnComments'

Question

So, I have a one to many relationship from Posts to comments:

type Comments {
  createdAt: DateTime!
  deleted: Boolean
  id: ID!
  posts: Posts @relation(name: "PostsOnComments")
  text: String!
  updatedAt: DateTime!
  user: String!
}

type Posts {
  caption: String!
  comments: [Comments!]! @relation(name: "PostsOnComments")
  createdAt: DateTime!
  displaysrc: String!
  id: ID!
  likes: Int
  updatedAt: DateTime!
}

and wish to run a mutation, which as well as deleting the connection between a post and a comment, attempts to update the field 'deleted, on Comments, to true:

mutation removeComment ($id: ID!, $cid: ID!, $stateB: Boolean) {
  removeFromPostsOnComments (postsPostsId: $id, commentsCommentsId: $cid, deleted: $stateB){
    postsPosts {
      __typename
      id
      comments {
        __typename
        id
        text
        user
        deleted
        posts {
          __typename
          id
        }
      }
    }
  }
}
  
Query Variables

{
  "id": "cj0qkl04vep8k0177tky596og",
  "cid": "cj1de905k8ya201934l84c3id"
}

But when I run the mutation I get the following error message:

GraphQL error: Unknown argument 'deleted' on field 'removeFromPostsOnComments' of type 'Mutation'. (line 2, column 74):
  removeFromPostsOnComments(postsPostsId: $id, commentsCommentsId: $cid, deleted: $stateB) {

As was explained to me here, only the link between Posts and comments is deleted, not the actual 'Comment' record itself. So my thinking is, as the record is not deleted, why can I not update the 'deleted' field?

I wish to do this so that it triggers a subscription, which is monitoring the updated field 'deleted'.

The generated mutation output is as follows:

  "data": null,
  "errors": [
    {
      "message": "Unknown argument 'deleted' on field 'removeFromPostsOnComments' of type 'Mutation'. (line 2, column 77):\n    removeFromPostsOnComments (postsPostsId: $id, commentsCommentsId: $cid, deleted: $stateB){\n                                                                            ^",
      "locations": [
        {
          "line": 2,
          "column": 77
        }
      ]
    }
  ]
}

As can be seen in the image, 'deleted' is definitely included in 'Comments' my GraphCool schema:

I reproduced your issue. First of all, you're getting the error message because deleted is not part of the arguments of the removeFromPostsOnComments-mutation, you also see that in the docs:

If you want to update the deleted field on the Comments type, you have to use the updateComments-mutation:

mutation {
  updateComments(id: "cj1de905k8ya201934l84c3id", deleted: true) {
    id
  }
}
