@AttilaVamos - any idea what the unittest failure is (I'm sure it's not related to this PR) and/or why there is no artifacts collected?

[jakesmith]

FWIW - I tested this PR based off 9.8.x to see if it was a 9.6.x issue only, and it did not fail there: #19474

NB: I also reran this PR and the unittests failure reoccured.
