Using mesh v1 how can I extend the schema on a field that has map with ids ?

[dimitrisfasoulas]

I have a rest api that when requesting GET on /getPosts I get the following schema:

[
  {
    "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
    "name": "string",
    "description": "string",
    "type": "string",
    "createdAt": "date",
    "updatedAt": "date",
    "createdBy": "string",
    "updatedBy": "string",
    "text": "string"
    "comments": {
      "title": "uuid",
      "title": "uuid",
      "title": "uuid"
    }
  }
]

There is another rest api that I can use to get the comments based on comment id /comments/{id}

The problem I have is that "comments" is a map of titles and uuids so the ids of the comments are returned as values in the "comments" part of the /getPosts.

If I use additionalTypeDefs :

additionalTypeDefs: /* GraphQL */ `
    extend type Post {
      provides: [comment!]
        @resolveTo(
          sourceName: "comments"
          sourceTypeName: "Query"
          sourceFieldName: "getCommentById"
          sourceArgs: { id: "{root.comments}" }
        )
    }

sourceArgs gets resolved to [object object] and as far as I understand I can't use JS to manipulate sourceArgs (like sourceArgs: { id: "{Object.values(root.comments)}" })

Using mesh v1 what options do I have to resolve this ?

comments under Post is an array of comments so in order to fill the missing fields, you should use Type Merging instead.
