It looks like we're occasionally seeing an error with ResizeObserver in CI on the CSV details page. This could be related to https://github.com/openshift/console/pull/9929.

Comment 1 Samuel Padgett 2021-09-10 12:29:50 UTC 
It might be this line: https://github.com/openshift/console/blob/master/frontend/public/components/markdown-view.tsx#L177
Comment 2 Samuel Padgett 2021-09-10 13:32:03 UTC 
Debugging this, I also see the following error in the JS console:

> unhandled error: ResizeObserver loop limit exceeded

It looks like we're resizing the frame, which triggers a resize event, which resizes the frame, etc.

Comment 7 Yanping Zhang 2021-09-26 01:57:10 UTC 
Search log in jobs agains, there is no error " Uncaught TypeError: Cannot read property 'firstChild' of null" now:
https://search.ci.openshift.org/?search=Cannot+read+property+%27firstChild%27&maxAge=48h&context=1&type=bug%2Bjunit&name=&excludeName=&maxMatches=5&maxBytes=20971520&groupBy=job
Also check on js console from cluster with payload 4.10.0-0.nightly-2021-09-23-210724, there is no "unhandled error: ResizeObserver loop limit exceeded" now.
The bug is fixed.
