"TypeError: Cannot read property 'toLowerCase' of undefined" when trying to list PRs

XMLWordPrintable

    • Blue Ocean 1.4 - beta 3, Blue Ocean 1.4 - beta 2

       

      The URL I'm trying to load is:

      http://_buildserver_/blue/organizations/jenkins/pipeline-github%2Fcore/pr/

      The page comes up with just the header and then the rest of the page is blank.

      In the JavaScript console:

          trejkaz would you mind capturing a HAR file that reproduces this bug?

          Tried today, but this time the page loaded, so it will have to wait until next time.

          I do see a lot of errors in the console on this run:

          GET http://_buildserver_/blue/rest/organizations/jenkins/pipelines/trunk-functional-matrix/pipelines/os=centos%20%7C%7C%20release-centos,test=lib/pipelines/case/pipelines/search_unsorted 404 (Not Found)

Unhandled Rejection:  TypeError: Cannot read property 'self' of undefined

    at blueocean.js:5910
    at <anonymous>

Unhandled Rejection:  TypeError: Already read
    at blueocean.js:3104
    at <anonymous>

          That said though, that original stack trace seems diagnosable because it's essentially an NPE. Each level in the stack just has to decide whether a null object is valid or not, and bam, you know where the problem is.

          Can you send through a HAR that captures that console error?

          Testing Notes:

          • Even though this appears to be an intermittent issue, it would be useful, going forward, to have an automated UI test which verifies the correct function of the Pull Requests tab. There might be one, but I've not found it anywhere in here.
          • This could end up as an offshoot of JENKINS-48125.
          • I've also not found any JS tests which target the PR tab, but that could be my lack of familiarity with those.
