Sometimes Blue-Ocean page get stuck in a step and displayed page is not refreshing. After Refreshing browser (with F5 for instance) you can see real step progress.
In browser console (chrome) I can see this:

[JENKINS-47584] Result screen not refreshing with error "Cannot read property 'self' of undefined"
jlp01 right - I think sophistifunk discovered this problem when working on something else recently.
What it appears to be is something causes a property in an object to not be serializable to json (perhaps a bug from a plugin), and it then skips over that field, vs logging the error. This means the front end expects to find some value that isn't there.
Do you think this is possibly the same problem as https://issues.jenkins-ci.org/browse/JENKINS-48198 ?
In fact jlp01 if you have the means - trying out https://github.com/jenkinsci/blueocean-plugin/pull/1625 would be interesting for you, as it may log the actual problem ...
After upgrading plugin, it stil happens in 1.4.1:
blueocean.js:58253 Unhandled Rejection: "TypeError: Cannot read property 'self' of undefined at ActivityService.bunkerKey (https://jenkins.eprinsa.es/adjuncts/ad10514b/io/jenkins/blueocean/blueocean-core-js.js:67429:26) at ActivityService.setItem (https://jenkins.eprinsa.es/adjuncts/ad10514b/io/jenkins/blueocean/blueocean-core-js.js:67472:26) at executeAction (https://jenkins.eprinsa.es/adjuncts/ad10514b/io/jenkins/blueocean/blueocean-core-js.js:43377:19) at ActivityService.res (https://jenkins.eprinsa.es/adjuncts/ad10514b/io/jenkins/blueocean/blueocean-core-js.js:43349:16) at https://jenkins.eprinsa.es/adjuncts/ad10514b/io/jenkins/blueocean/blueocean-core-js.js:67744:40 at <anonymous>"
As you mention, I guess it's similar but not same problem as in 48198 issue.
vivek the last report by jlp01 looks like a SSE problem. An event is coming in, updating the run information but we might not have a reference... perhaps the bunker here needs to be more resiliant to those problems? WDYT sophistifunk?
jamesdumay yes it seems very different from the toLowerCase on an undefined pointer.
It's probably unrelated to the deserialisation problem. Looks like a response / message is coming in from the server with no payload. We could cover up the exception in the client-side by simply ignoring `setItem(undefined)` but then we'd still be doing whatever is causing the response to be null in the first place.
sophistifunk I see 404s in the attached HAR. Is it the case where frontend code is not handling 404 well and goes ahead trying to render it?
It shouldn't, but it's hard to say for sure. Without a local replication to step through there's just not a lot of insight I can give, the karaoke code is too convoluted.

added a comment - I am able to reproduce this in a declarative pipeline that has a user input step. After pressing on the button to proceed, sometimes the pipeline continues to the next stage without refreshing the page, other times the UI just hangs there until I refresh it although things are happening and visible in the standard console logs.
Jenkins version: 2.180
Tried with a few different versions of Blue Ocean to no avail: 1.17.0. 1.11.0, 1.8.0, 1.7.3

added a comment - Could we please reopen this?
As I indicate in my last comment, it still happens. I re-open it.
