Comment (by SergeyBiryukov):

 Replying to [comment:7 hellofromTonya]:
 > I'm curious if the `null to non-nullable` has already been resolved
 indirectly by a fix that then invoked one of the formatting functions.

 Yes, this notice appears to come from `untrailingslashit()` called on a
 `null` value.

 That would be a duplicate of #54997. The only known instance in core was
 resolved in [54349] and [54351] / #55967.
