Issue with Parsing JSON Response in Custom Code

Hey all, another quick question (effect-http related).

I have this code snippet for fetching some data from a public API:

const getArtist = Http.request
  .get("https://musicbrainz.org/ws/2/artist/?query=ac%5C%2Fdc&fmt=json")
  .pipe(
    Http.client.fetch,
    Effect.andThen(Http.response.schemaBodyJson(SearchResult)),
    Effect.catchTag("ParseError", (e) =>
      Effect.fail(ServerError.internalServerError(e))
    ),
    Effect.tap(Console.log),
    Effect.scoped
  );


I ensured that the URL returns a correct JSON object, as I tested it in Insomnia.

SearchResult is simply a Schema.Struct:

export const SearchResult = s.Struct({
  created: s.String,
  count: s.Number,
  offset: s.Number,
  artists: s.Array(ArtistS),
});


Where ArtistS is a big type/Struct containing all the data returned from the API. The result in general conforms to what is returned from the API.

However, for some reason, I seem to get this error:

{"_id":"ParseError","message":"{ created: string; count: number; offset: number; artists: ReadonlyArray<{ id: string; type: string; type-id: string; score: number; name: string; sort-name: string; country: string; disambiguation: string; area: { id: string; type: string; type-id: string; name: string; sort-name: string; life-span: { ended?: boolean | undefined } }; begin-area: { id: string; type: string; type-id: string; name: string; sort-name: string; life-span: { ended?: boolean | undefined } }; ipis: ReadonlyArray<string>; isnis: ReadonlyArray<string>; life-span: { begin: string; ended?: boolean | undefined }; aliases: ReadonlyArray<{ sort-name: string; type-id: string; name: string; type: string; locale?: string | undefined; primary?: boolean | undefined; begin-date?: string | undefined; end-date?: string | undefined }>; tags: ReadonlyArray<{ count: number; name: string }> }> }\n└─ [\"created\"]\n   └─ is missing"}


I'm not sure why it's saying created is missing; Insomnia showed it to be correct. That leads me to believe I'm not doing something right with the fetch? I'm just not sure exactly what at present.
