Possible error in Yandex webmaster: Description meta tags are missing. The pages look like duplicates, but these pages are not in the site's admin area. What to do?

Question

Search Engine Optimization

The webmaster reports a possible problem "Description meta tags are missing". These pages look like duplicates. They are not in the admin panel of the site, so I cannot write descriptions for them (and the meaning).
The site is on WordPress, the yoastseo plugin is installed.
What can be done in this case?
Is it possible to just close these pages in robots.txt or will it affect rankings?

Answer 1

Good afternoon.
Close all questionable pages in robots.txt -

and also in Yoast, go through the settings and prohibit indexing of these very types of pages that look like duplicates :). It won't get worse for sure!

Answer 2

It is better to make redirects from them to the main versions of the pages. This is reinsurance.
