Failing to run google_search_features.js

Very cool usages!

Unfortunately I'm having problems running the Google Search example, my output is:

oyvinds-mac:puppeteer-examples osmestad$ node google_search_features.js

I'v tried with Node v8.12.0 and v10.13.0 any idea what might be causing this?
(lazyimages_without_scroll_events.js worked for me)

If I revert Puppeteer to 1.7.0 it works :-) so I assume it is something that has changed between 1.7 and 1.8?

I couldn't fix it by downgrading to 1.7.0 - still get the error from above

I also tried it. It works with v1.7.0 but does not work with v1.8.0.
It seems that TracingStartedInPage can not be found.
