Google Search Console reports error for ‘noindex’ tag on sitemap

My sitemap is dynamically generated by Yoast SEO WordPress plugin, and is returned with noindex. I submitted the sitemap URL to Google Search Console, but it reports an error:

Submitted URL marked ‘noindex’

I checked with Yoast & other sitemap generators–they all mark sitemaps as noindex by design, to prevent them from appearing in Google search results. It logically makes sense, but then why is Google Search Console reporting it as an error? How do I reconcile this?
