Every page must contain a meta description
Well, I see things rather differently.
The noindex meta tag prevents the page from being included in the index; meta description is not used by search engines for indexing but to display information in the search results.
So, when a page is noindexed the meta description tag is redundant.
By the way, very often you may find that the meta description in the search results is completely different than the one you defined, it’s because Google decides what best describes the content of your site. So I wouldn’t pay much attention to this tag.
