getArticle not working with special characters in title

The program below works for en.wikipedia.org but for openwetware.org it outputs "Got: undefined" and this is the actual response returned from the server:

{"warnings":{"main":{"*":"Unrecognized parameter: rand."}},"batchcomplete":"","query":{"pages":{"-1":{"title":"Main%20Page","invalidreason":"The requested page title contains invalid characters: \"%20\".","invalid":""}}}}

#!/usr/bin/env node

var mw = require('nodemw');

var client = new mw({
  protocol: "https",
  server: "openwetware.org",
  path: "/w",
  debug: true
});

client.getArticle("Main Page", function(err, data) {
  if(err) {
    console.error(err);
    process.exit(1);
  }

  console.log("Got:", data);
});

I believe you have to replace spaces in the title with underscores.

It works with spaces. I believe this pull request solves my problems.

But it does not work for me (with your fix applied) :)

info:    nodemw v0.12.0 (node.js v6.12.0; linux x64)

Ah yes there was another problem. The openwetware.org mediawiki installation has a different script path so the path option had to be set to "/mediawiki".

The script path on a given wiki installation is available via the Special:Version page. It would be really cool if nodemw could auto-detect the script path given e.g. a URL to an arbitrary page on the wiki.
