Describe the bug

• Node.js version: v14.14.0
• OS & version: Fedora 33

When the server returns an error code with JSON body, and I try to parse it using .json() and {throwHttpErrors: false}, I get the following error:

TypeError: Cannot read property 'request' of undefined
    at /path/to/my/project/node_modules/got/dist/source/as-promise/index.js:157:48
    at processTicksAndRejections (internal/process/task_queues.js:93:5)

Actual behavior

TypeError is thrown

Expected behavior

Returning the body of response, parsed as JSON (matching the behavior of {responseType: 'json', resolveOnlyBody: true}, as documented)

Code to reproduce

https://runkit.com/embed/3tt06wxjbio1

const got = require("got");
await got("https://api.github.com/user", {throwHttpErrors: false}).json();

Checklist

• I have read the documentation.
• I have tried my code with the latest version of Node.js and Got.
