failing without clear reason about node-fetch

[OliverJAsh]

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

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)
    at ClientRequest.emit (node:events:518:28)
    at Socket.socketErrorListener (node:_http_client:500:9)
    at Socket.emit (node:events:518:28)

    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  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
