After PR #154081 was merged, @sscalpone commented on the PR asking for changes to the error that in this PR has now been moved to this line. I have added the above suggestion based on the suggested wording from @sscalpone with my own additional suggested changes. Please everyone let me know what you think about the above suggestion.
