I prefer simplicity and using the first example but I’d be happy to hear other options. Here’s a few examples:

HTTP/1.1 403 POST /endpoint
{ "message": "Unauthorized access" }

HTTP/1.1 403 POST /endpoint
Unauthorized access (no json)

HTTP/1.1 403 POST /endpoint
{ "error": "Unauthorized access" }

HTTP/1.1 403 POST /endpoint
{
  "code": "UNAUTHORIZED",
  "message": "Unauthorized access",
}

HTTP/1.1 200 (🤡) POST /endpoint
{
  "error": true,
  "message": "Unauthorized access",
}

HTTP/1.1 403 POST /endpoint
{
  "status": 403,
  "code": "UNAUTHORIZED",
  "message": "Unauthorized access",
}

Or your own example.

    Anything but the last one. Don’t duplicate the http code in the body, else you’re now maintaining something you don’t need to maintain.

    I’m not a fan of codes that repeat information in the body either, but I think if you had used a different example like “INVALID_BLAH” or something then the message covered what was invalid, then it would be fine. Like someone else said, the error data should be in an object as well, so that you don’t have to use polymorphism to figure out whether it’s an error or not. That also allows partially complete responses, e.g. data returns, along with an error.
