I would like to do:
"status":"fail", {"error":{"isAuthorized":false,"password":"wrongPassword"}}

You can use a struct and serializeToJsonString (or pass the struct to res.writeJsonBody):

struct PasswordError {
  bool isAuthorized;
  string password;
}
struct ErrorStatus {
  string status;
  PasswordError error;
}

logInfo(%s, ErrorStatus("fail", PasswordError(false, "wrongPassword")).serializeToJsonString());
