ky/distribution/errors/HTTPError.js

Tiny and elegant HTTP client based on the Fetch API

import { KyError } from './KyError.js';
/**
Error thrown when the response has a non-2xx status code and `throwHttpErrors` is enabled.

The error has a `response` property with the `Response` object, a `request` property with the `Request` object, an `options` property with the normalized options (either passed to `ky` when creating an instance with `ky.create()` or directly when performing the request), and a `data` property with the pre-parsed response body. For JSON responses (based on `Content-Type`), the body is parsed using the `parseJson` option if set, or `JSON.parse` by default. For other content types, it is set as plain text. If the body is empty or parsing fails, `data` will be `undefined`. To avoid hanging or excessive buffering, `error.data` population is bounded by the request timeout and a 10 MiB response body size limit. The `data` property is populated before `beforeError` hooks run, so hooks can access it.

The response body is automatically consumed when populating `error.data`, so `error.response.json()` and other body methods will not work. Use `error.data` instead. The `error.response` object is still available for headers, status, etc.

Be aware that some types of errors, such as network errors, inherently mean that a response was not received. In that case, the error will be an instance of `NetworkError` instead of `HTTPError` and will not contain a `response` property.
