'X-Robots-Tag'에서 'noindex' 오류를 수정하는 방법

Hi all
I have indexed my site to google and get error “No: ‘noindex’ detected in ‘X-Robots-Tag’”.
How to remove this header tag ?

It may have something to do with this Search engines now blocked from indexing non-canonical pages

thank you
so do i have to rebuild app to apply this merge?

Yes, update to latest.
