I have a custom news template in sitepages in a site collection which I do a "copy" and then publish whenever I want to make a new news article.
However, these news articles managed properties (firstpublisheddate, likescount, comments etc) is null when I extract them from the search schema, even if these properties should have data.
Even if the social bar contains likes or comments it does not show in a search connected to their managed properties.
In the search schema I have mapped (as a example) the CP ows_FirstPublishedDate to the FirstPublishedDate MP. Is there any reason why managed properties from the search schema is null, and is there anything I could try?
