UPDATE: this seems to be happening from time to time, on Bens instance. It may not be related to auth. There is always a pattern of some JSON returned in the response, and then truncated, and then a HTML stacktrace.
Uncovered by bwalding:

The original trace came from an internal instance - bwalding can supply more information and request info on the instance if required
This points to this line: https://github.com/jenkinsci/rebuild-plugin/blob/master/src/main/java/com/sonyericsson/rebuild/RebuildAction.java#L152 possibly
Currently he is using google auth for identity, and it seems to happen after 30 minutes.
Reloading the page causes things to work again just fine.
On theory is that session is not re-established cleanly and the null is the api is trying to access things in an unauthenticated state.
Investigation required.

[JENKINS-36980] intermittent NPE/500 errors after leaving blue ocean open for a while
vivek OK I left a session open for 35 minutes with a default jenkins setup (with the authentication on) and there are various failures that happen when you try and use it again without refreshing the page. Not the same errors as ben but seems related to session time out/stale-ness.
michaelneale Session timeout can be handled better once we have JWT support in, its still a WIP but not on master yet.
vivek good to know. I suspect this is just a particularly hard failing of session timeout, but that is just an educated guess.
/blue/rest/organizations/jenkins/pipelines/<job>/runs/
I don't think it's directly a session / auth issue - this was generated after I had refreshed my main app to ensure session was up to date.

(I did not chop that exception - I just put what was in the chrome panel)
vivek have updated the ticket - not related to timeouts/session I think. There is a NPE somewhere when it is rendering _links now:
,"href":"/blue/rest/organizations/jenkins/pipelines/ecs-apps/pipelines/cloudbees-console/pipelines/cloudbees-console-frontend/branches/production/runs/13/testReport/"}},"_class":"hudson.tasks.junit.TestResultAction","failCount":0,"skipCount":0,"totalCount":42,"urlName":"testReport"},{"_
is where it gets to before NPE happens. the json stops at that point.
Still not sure what plugin could be causing it.
michaelneale Ah, I see. This is happening collecting underlying actions. The code that collects these actions, should skip misbehaving actions instead failing completely. I will work on a fix tomorrow.
Interesting, in the repsonse body, I saw:
