JSON Schema: Cannot define "Array of Objects"

[ddcollins]

Edit: Issue created #2052

I've been unsuccessful in being able to define a return of an array of objects.

  - name: AchievementsAPI
    transforms:
      - resolversComposition:
          - resolver: 'Query.*'
            composer: ./src/middleware/reformat-rest-response.js
    handler:
      jsonSchema:
        baseUrl: ${ACHIEVEMENTS_HOST}
        baseSchema: ./src/json-schemas/achievements-api/base-schema.json
        errorMessageField: detail
        disableTimestampScalar: True
        operationHeaders:
          Content-Type: application/json
          Accept: application/json
          X-Api-Token: ${ACHIEVEMENTS_API_TOKEN}
          X-USER-ID: "{context.headers['x-user-id']}"
        operations:
          - type: Query
            field: achievements
            path: /achievements
            method: GET
            responseTypeName: "[Achievement]"

My base schema defines:

{
  "type": "object",
  "properties": {},
  "definitions": {
    "Achievement": {
      "type": "object",
      "properties": {
        "id": {
          "type": "string"
        },
        "categoryId": {
          "type": "string"
        },
        "name": {
          "type": "string"
        },
        "createdAt": {
          "type": "string"
        },
        "updatedAt": {
          "type": "string"
        }
      }
    }
  }
}

But I get the error:

TypeError: Cannot read property 'match' of null

  locations: [],

}

I've also tried defining an array of items in a schema file:
./src/json-schemas/achievements-api/achievements.response.json

{
  "$ref": "#/definitions/AchievementsOutput",
  "definitions": {
    "AchievementsOutput": {
      "type": "array",
      "items": {
        "$ref": "#/definitions/Achievement"
      }
    }
  }
}

With mesh file definition of:

  - name: AchievementsAPI
    transforms:
      - resolversComposition:
          - resolver: 'Query.*'
            composer: ./src/middleware/reformat-rest-response.js
    handler:
      jsonSchema:
        baseUrl: ${ACHIEVEMENTS_HOST}
        baseSchema: ./src/json-schemas/achievements-api/base-schema.json
        errorMessageField: detail
        disableTimestampScalar: True
        operationHeaders:
          Content-Type: application/json
          Accept: application/json
          X-Api-Token: ${ACHIEVEMENTS_API_TOKEN}
          X-USER-ID: "{context.headers['x-user-id']}"
        operations:
          - type: Query
            field: achievements
            path: /achievements
            method: GET
            responseSchema: ./src/json-schemas/achievements-api/achievements.response.json

but I get Mesh error:

$ /app/node_modules/.bin/graphql-mesh serve
- Generating Mesh schema...
error: Unable to start GraphQL Mesh: Type with name "AchievementsOutput" does not exists
