If non-OK HTTP response fails to parse as XML, no info is included

[alxndrsn]

Observed

Non-XML response bodies are parsed as XML, resulting in an anonymous error.

Expected

It would be helpful if the resulting error included:

• http status code
• response headers
• response body

Environment

Tested with:

• v8.0.4

Repro

const express = require('express');
const app = express();
app.all('/*', (req, res) => res.sendStatus(502));

(async () => {
  const port = await new Promise(resolve => {
    const server = app.listen(0, () => resolve(server.address().port));
  });

  const Minio = require('minio');
  const minioClient = new Minio.Client({ endPoint:`localhost`, port, useSSL:false });

  try {
    await minioClient.getObject('abfg', 'b');
  } catch(err) {
    console.log(err);
    _err = err;
  }
})();

The resulting error looks like:

{
  name: 'S3Error',
  amzBucketRegion: undefined,
  amzId2:  undefined,
  amzRequestid:  undefined,
}

with stack:

I see in 8.0.7 the error is still anonymous, but the message prop can be parsed as it now includes the response status code:

Request failed after 1 retries: Error: Retryable HTTP status: 502
