browser.takeScreenshot() hangs on linux and chrome

[jniles]

Bug report

It appears that await browser.takeScreenshot() is hanging in my configuration. I've confirmed that await browser.getTitle() works.

Control flow is off and I'm using mocha + chai-as-promised to run tests.

My code looks like this:

 it(`should take a screenshot`, async () => {
    console.log('x');
    // take a screenshot
    const n = await browser.getTitle();
    console.log('n', n);
    const x = await browser.takeScreenshot();
    console.log('y');
  });

And the result:
