The log in the backfill action test does say that the task was created. Here's the task view for one of them: https://firefox-ci-tc.services.mozilla.com/tasks/WFW5OH8RTIW4eLfitiGyyw The wdspec task *is* listed as a dependent (though it failed): https://firefox-ci-tc.services.mozilla.com/tasks/GWbKHNOgTHqzNwDDdO3UJw But for some reason treeherder doesn't display it. Could there have been some kind of treeherder ingestion issue around this time? Things at least seem to be working from the taskgraph point of view. Sheriff note: if you run into this again, it'll be possible to view the task by drilling into the task view of the "backfill" action, and then clicking "See more" to find the "Dependents" section. The requested task should show up there, and clicking it will display its state and a link to the log (under "Artifacts"). I'm only suggesting this as a temporary workaround, not a solution to this bug.
