`body` is a String, so it has no `error_type` property. Either remove the quotes around it, or parse the JSON: `JSON.parse(body).error_type` – blex Dec 12 '20 at 13:15

It worked with JSON.parse. Thanks buddy – Shubham Bhardwaj Dec 12 '20 at 13:17

Why all those tags? There's no array, no object and it has nothing to do with C. – Andreas Dec 12 '20 at 13:19

You have enclosed the value with single quotes ('), which means that the type of body is string, not object. An object should be enclosed with curly braces ({}).
Compare the following:
const someString = '{foo: "bar"}';
const anObject = {foo: "bar"};
For your use case:
const body = {
error_type: 'OAuthException',
code: 400,
error_message: 'This authorization code has been used',
};
console.log(body.error_type);
If you are receiving body from elsewhere and the value is already a string, you can parse it as an object using JSON.parse(body).
