I'm getting the following error:
BadPayload "Expecting an object with a field named `id` but instead got: {}"
{ status = { code = 200, message = "OK" }, headers = Dict.fromList [(
"Cache-Control","no-cache"),("Content-Type","application/json;
charset=utf-8"),("Expires","-1"),("Pragma","no-cache")], url =
"http://localhost:4000/players/9";, body = "{}" }
How should I structure my Http.request to expect an empty body?
