OK I found something which might be the reason you're hitting this.
There was a fix that was backported to newton upstream:
https://review.opendev.org/#/q/I11746d1ea996a0f18b7c54b4c9c21df58cc4714b
Which causes a regression which was fixed and backported through to ocata but not newton because newton was end of life at that point:
https://review.opendev.org/#/q/I7fde8ce9dea16679e76b0cb2db1427aeeec0c222
So it looks like you'd need to backport that ocata fix to your internal newton branch:
