Initial problem from web-vitals package - https://github.com/GoogleChrome/web-vitals/issues/313

Following the discussion in web-vitals repo, we can still report 0 values and add just fix for BFCache case - https://github.com/Zizzamia/perfume.js/pull/221

i believe we are hitting this error as well fwiw

undefined is not an object (evaluating 'e.entries[0].requestStart')

@scamden what version are you using?

Mar 23 '24 07:03 Zizzamia

Mar 25 '24 18:03 scamden

I'm upgrading to 9.4 and will let you know if we see again

Also, curios, what version of web-vitals are you resolving, maybe we need to upgrade from Perfume side as well.

@scamden do you still see the issue after upgrade?

Haven't seen it since to my knowledge (although we had only seen it once so sample size is pretty low for this data :P )

Thanks for the tip on upgrading! Perfume is a great package :)

Ok, so I think it's safe to close this for now.

I will reopen this if this issue happens again.
