Get helper for posts doesn't return author name?

I am using Ghost (Pro). On my home page, I want to show the 3 latest posts for a selection of tags. I inserted the following code using the get helper:

{{#get "posts" filter="primary_tag:technology"}}
    {{#foreach posts limit="3"}}
        {{> "post-card"}}

The problem I am facing with this is that the post-card that is rendered doesn’t have the tag or author info. While I am ok with the tag not showing up, it would be nice to know why it isn’t showing up (same for author info).

You need to explicitly get authors -

{{#get "posts" filter="..." include="authors"}}
