Additional context

How can I get more info on this bug? why reason is not defined?

I am facing the same issue. We're using error.message and the "reason" is empty. Reduced test case:

import fetch from 'node-fetch';
fetch('http://localhost:1234/regdvfs');

Result:

file:///Users/oliver/Code/unsplash/unsplash-web/node_modules/node-fetch/src/index.js:108
			reject(new FetchError(`request to ${request.url} failed, reason: ${error.message}`, 'system', error));
			       ^

FetchError: request to http://localhost:1234/regdvfs failed, reason:
    at ClientRequest.<anonymous> (file:///Users/oliver/Code/unsplash/unsplash-web/node_modules/node-fetch/src/index.js:108:11)

  type: 'system',
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED',
  erroredSysCall: undefined
}

error.message:

FetchError: request to http://localhost:1234/regdvfs failed, reason:

I'd expect something like this:

FetchError: request to http://localhost:1234/regdvfs failed, reason: ECONNREFUSED

mine was a failing dns service

Ah, but I think this is still an issue—that node-fetch doesn't return a more informative error message?
