This is user error, not a break. Discovered that I was incorrectly mapping in a list context in a script. Reopening just for the warning (which was not the cause below) at a lower severity.

I0811 10:53:44.397656 48614 table_printer.go:45] Unable to decode server response into a Table. Falling back to hardcoded types: attempt to decode non-Table object
4.4.11
returns the correct output "4.4.11" from the example above, but the error continues to print. We should understand why this warning is being printed in a jsonpath context (it should not, because jsonpath printer shouldn't need tabular output). This might be breaking other printer logic. I would expect to not see this warning and for us to not request tabular output (which from the debug above looks like we aren't doing).
opened this upstream: https://github.com/kubernetes/kubernetes/pull/93940 waiting on upstream merge, then will be pulled into oc with next vendor bump. Next vendor bump to kubernetes 1.20 will bring this in. Moving to upcoming sprint. We will not carry a patch for this, still waiting on next vendor bump. Still waiting on next vendor bump to bring in the fix: https://github.com/kubernetes/kubernetes/pull/93940 Still waiting on bump to kubernetes 1.20, adding UpcomingSprint. This bug hasn't had any activity in the last 30 days. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're marking this bug as "LifecycleStale" and decreasing the severity/priority. If you have further information on the current state of the bug, please update it, otherwise this bug can be closed in about 7 days. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. Additionally, you can add LifecycleFrozen into Keywords if you think this bug should never be marked as stale. Please consult with bug assignee before you do that. This should merge in https://github.com/openshift/oc/pull/648 Added upcoming sprint to track the vendor bump This bug hasn't had any activity in the last 30 days.

The fix has landed in oc, moving to Modified. QA, please verify, thanks! The LifecycleStale keyword was removed because the bug moved to QE and the bug got commented on recently. The bug assignee was notified. Can't reproduce now:

Falling back to hardcoded types: attempt to decode non-Table object $ This is a fundamental regression with wide ranging impact to scripting and administrative use and could silently break or cause failures in production workloads on upgrade. While we may officially support N-1, we treat regressions like this as blockers. I consider this a 4.6 release blocker and may not be deferred without significant justification.
