CDP.Close() not working with Chrome 59 on macOS

Hi, I’m trying to do the following actions:

1. open a new (headless) Chrome tab
2. navigate to an URL
3. take e screenshot
4. close Tab

And closing tab doesn’t work. In fact, if I do a http://localhost:9222/json/list all the tabs opened at specified pages are listed.

Basically, the code is the following:

...
const target = await CDP.New({ port: this.options.port || 9222 });
const tab = await CDP({ target });     
const tabId = tab.target.id;      
const { Page, Emulation } = tab;
      
await Promise.all([
  Page.enable(),
  Emulation.setDeviceMetricsOverride(options.metrics),
  Emulation.setVisibleSize({ width: options.metrics.width, height: options.metrics.height }),
  Emulation.forceViewport({ x: 0, y: 0, scale: 1 }),
]);
await Page.navigate({ url: url });
await Page.loadEventFired();      
let { data } = await Page.captureScreenshot({ format: 'png', fromSurface: true });

// do something with data... 
// close tab   

await CDP.Close( {id: tabId});

I’ve also tried using Runtime:

await tab.Runtime.evaluate({expression: 'window.close();'})

but again, tabs stay open. Many thanks.

Yeah, that makes sense. I’ve opened a PR that adds a general note. Feel free to tweak it or let me know how you’d like it to change and I can adjust the PR.

FYI for anybody else that lands here, the bug has been fixed in Chrome Canary: https://www.google.com/intl/en/chrome/browser/canary.html

@cyrus-and perhaps we should comment about this in the readme where appropriate? If you agree I’ll open a PR.
