r2.post not working vs fetch

[DevBrent]

At my wits end trying to get this POST to return properly.

What else does r2 do to the request vs fetch? Something is wrong. I've tried using different initialization methods and alternate response management to try to get a working result.

Universal variables for all four examples:

const url = 'https://example.com/path';
const params = { example: 'request data', other_data: 'test' };

const body = Object.keys(params).map(key => encodeURIComponent(key) + '=' + encodeURIComponent(params[key])).join('&');

const headers = {
  'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
};

Broken, returns 400 error html:

const r2_example = await r2.post(url, {
  headers,
  body
});
console.log('r2', await r2_example.text);

Broken; alternate configuration, alternate response handling, still returning 400 error in html:

const r2_example_2 = await r2({
  url,
  body,
  method: 'POST',
  headers,
});
console.log('r2_2', await (await r2_example_2.response).text()); // 400 Bad Request

Working example with raw Header/Body

const fetch_example = await fetch(url, {
  method: 'POST',
  headers,
  body
});
console.log('fetch', await fetch_example.text());   // Proper result

Working example with node-fetch.Headers (globals created by r2) and Buffer.from(string).

const fetch_example_with_headers = await fetch(url, {
  method: 'POST',
  headers: new global.Headers(headers),
  body: Buffer.from(body)
});
console.log('fetch_example_with_headers', await fetch_example_with_headers.text()); // Proper result

I just confirmed replacing node-fetch 2.0.0-alpha.8 with 2.2.0 resolves this issue. In our other environments running yarn upgrade r2 resolved the issue as well even without merging #66
