Unable to get chrome logs

I’m trying to get chrome’s logs when launched through WebdriverIO. These are the options I use to start chrome with:

{
      desiredCapabilities: {
        browserName: 'chrome',
        chromeOptions: {
          binary: path.resolve('/usr/bin/google-chrome'),
          forceDevToolsScreenshot: true,
          args: [
            '--load-and-launch-app=' + path.resolve('./build/chrome/'),
            '--enable-logging',
            '--v=1',
            '--no-sandbox',
          ]
        }
      }
}

When I run my script through Mocha, Chrome (and the external app) launches, but I do not see a chrome_debug.log file in my user directory (which should be ~/.config/google-chrome/ if I’m not mistaken).

If I do the same manually, as in, launching chrome via the command line google-chrome --enable-logging --v=1, the file does indeed appear, which leads me to believe this might be an issue with WebdriverIO.

I’m using Ubuntu 14.04 (Chrome 48), but I’ve tried doing the same on OSX(Chrome 49), with the same result.

I think this is something that needs to be fixed in the chromedriver project.

If I set CHROME_LOG_FILE to a filename before running wdoi, then Chrome writes the log to the filename. (If I don’t set CHROME_LOG_FILE, then it doesn’t seem like Chrome writes its log file anywhere, which isn’t consistent with the behavior I get from just launching Chrome with --enable-logging.)
