ERR_INVALID_URL on new URL

Environment details

• OS: MacOS 10.14
• Node.js version: v11.1.0
• npm version: 6.4.1
• googleapis version: v35.0.0

Steps to reproduce

1. ? use https://github.com/gsuitedevs/node-samples/blob/master/drive/quickstart/index.js
2. ? node index.js

When I try to authenticate with the quickstart script it gave me an error ERR_INVALID_URL. I noticed that starting url (for example : http://localhost:8000) is missing in the new URL constructor.

Original code :

    const server = http
      .createServer(async (req, res) => {
        try {
          if (req.url.indexOf('/oauth2callback') > -1) {
            const qs = new url.URL(req.url).searchParams;
            res.end('Authentication successful! Please return to the console.');
            server.destroy();
            const {tokens} = await oauth2Client.getToken(qs.get('code'));
            oauth2Client.credentials = tokens;
            resolve(oauth2Client);
          }
        } catch (e) {
          reject(e);
        }
      })
      .listen(3000, () => {
        opn(authorizeUrl, {wait: false}).then(cp => cp.unref());
      });

Modified code :

const server = http
    .createServer(async (req, res) => {
      try {
          if (req.url.indexOf('/oauth2callback') > -1) {
			// Now use keys origin url
            const qs = new url.URL(keys.javascript_origins[0] + req.url).searchParams; 
            res.end('Authentication successful! Please return to the console.');
            server.destroy();
            const {tokens} = await oauth2Client.getToken(qs.get('code'));
            oauth2Client.credentials = tokens;
            resolve(oauth2Client);
          }
        } catch (e) {
          reject(e);
        }
      })
      .listen(8000, () => {
        opn(authorizeUrl, {wait: false}).then(cp => cp.unref());
      });

@HeadFox thank you for pointing it out
try to use the following:

const server = http
        .createServer(async (req, res) => {
          try {
            if (req.url.indexOf('/oauth2callback') > -1) {
              const qs = querystring.parse(url.parse(req.url).query);
              res.end('Authentication successful! Please return to the console.');
              server.destroy();
              const {tokens} = await oauth2Client.getToken(qs.code);
              oauth2Client.credentials = tokens;
              resolve(oauth2Client);
            }
          } catch (e) {
            reject(e);
          }
        })
        .listen(3000, () => {
          // open the browser to the authorize url to start the workflow
          opn(authorizeUrl, {wait: false}).then(cp => cp.unref());
        });

also please refer to the drive/quickstart.js sample.
