Query App Discount Code Private Metafields

[alecbarnard]

I have an app that creates discount codes, similar to the app described in this tutorial: https://shopify.dev/apps/discounts/create

These discounts are created as codeAppDiscounts. I would like to be able to query this with GraphQL and access the private metafields. The metafields are created with a given namespace and key. 

I've tried a query like this but getting 500 errors back.

Query

{
  discountNodes(first: 1) {
    edges {
      node {
        id
        privateMetafield(namespace: "my-namespace", key: "my-key") {
          value
        }
      }
    }
  }
}

Error:

{
  "errors": [
    {
      "message": "Internal error. Looks like something went wrong on our end.\nRequest ID: cb1f7743-b8f5-4cc5-9aeb-856a32385667 (include this in support requests).",
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "requestId": "cb1f7743-b8f5-4cc5-9aeb-856a32385667"
      }
    }
  ]
}

Any ideas what is going wrong or how I might access these metafields? Thanks!

Mistake on my part - this should just use metafield instead of private metafield 

        metafield(namespace: "my-namespace", key: "my-key") {
          value
        }
