Describe the Bug

As per my conversation with @AlexRothwell , when running Lighthouse on big websites, it shows PROTOCOL_TIMEOUT error.

This is actually a known issue with Lighthouse CLI library. The error refers to the situation when Lighthouse has been waiting for Chrome to respond to a single command for more than 30 second
See GoogleChrome/lighthouse#6512

How we could resolve this

As per my conversation @amankumarrr , we should use PageSpeed Insights API to run Lighthouse instead which is proven to be much faster and more reliable than using Lighthouse CLI library.

Tasks

• Use PageSpeed Insight to run Lighthouse audit

Thanks!

Use PageSpeed Insight to run Lighthouse audit

Done - PageSpeed Insight is now being used to run Lighthouse audit

Based from testing on several websites, this seems to be much faster and more reliable than using Lighthouse-ci library
