You can additionally use libraries that perform type validation of your json, such as Sparkson. They allow you to define a TypeScript class, to which you'd like to parse your response, in your case it could be:

import { Field } from "sparkson";
class Response {
   constructor(
      @Field("name") public name: string,
      @Field("error") public error: boolean
   ) {}
}

The library will validate if the required fields are present in the JSON payload and if their types are correct. It can also do a bunch of validations and conversions.
