1177208 - Cannot cancel all jobs with error "Failed to cancel all jobs:undefined"

Status: RESOLVED INCOMPLETE

(Tree Management :: Treeherder, defect, P2)

Description

[(no longer active)]

I got this when trying to cancel https://treeherder.mozilla.org/#/jobs?repo=try&revision=429d0094d340.  I had retriggered a bunch of tests, so that may be related.

This message is being generated here:

Which is being called from here, presumably after the http post to the build api fails:

https://github.com/mozilla/treeherder/blob/e8ebf10689e33519cb6a8980dc4ffd4ce30651b8/ui/js/controllers/jobs.js#L202

It's difficult to know exactly what's happening here, aside from the fact that we don't have enough data to generate a good error message. Reading the angular docs, it looks like we should be calling the special $http promise .error callback, which gives us a bit of extra information:

https://docs.angularjs.org/api/ng/service/$http

If I were going to work on this bug, that'd be where I'd start.

This area of the code has been changed a few times since, including improving the error messages. If this happens again, please reopen :-)
