Frequent console errors and reviews loading really long

Hi all, would like to report potential issue.

I think this week, or around 5 days I experience frequent slowness during reviews and new items learning. I was trying to debug the issue and catch it with my console open.

What I found:

ping to wanikani.com was excellent, so it is not a general latency, e.g. it was:

64 bytes from 99.86.195.67: icmp_seq=365 ttl=248 time=7.472 ms

64 bytes from 99.86.195.67: icmp_seq=366 ttl=248 time=13.580 ms

64 bytes from 99.86.195.67: icmp_seq=367 ttl=248 time=11.325 ms

64 bytes from 99.86.195.67: icmp_seq=368 ttl=248 time=15.409 ms

In the same time, when slowness is happening, errors in console are shown:

I am not sure how helpful it is, but at least I confirmed it is coming from node package of wanikani.

Please help to pass to your dev team.

Thank you!

I tried to see if it is any of my chrome extensions blocking anything.

I think it is not, because it was slow on loading main page and also showed an error in console:
