When I tried to test for speed at our site, I got the error below. Not sure what wrong. I tried other service like pingdom to check and the site load fine. Hope someone can lend an insight. Site link: https://www.insperity.com/blog/calling-in-sick-2/

Could you confirm a couple of things. 1. Are you using the API, the PSI page (developers.google.com/speed/pagespeed/insights), Developer tools audit or a local copy of Light House running on your own server? 2. Are you getting this error across the site or only on the page you linked (as that page returns a 404 header so will not scan anyway). – Graham Ritchie

This was a bug in the PageSpeed Insights frontend. It was fixed soon after.

I'll chime in to say that I'm getting "There was a problem with the request. Please try again later." on the PageSpeed Insights page.

But also the "Cannot read property 'length' of undefined" error in Lighthouse.

I tested it on several sites other than my own and they all come back with the same error message.
