This is correct so far, although <#if outFile?cotains(m.item.link)>
would be nicer.

(It is an error since ${Expression} only makes sense put directly into
static text or into a string literal. Elsewhere you can you just use
Expression as is.)

(I assume there will be something else next to the "item" key in that
map, or else that whole map could be eliminated, of course.)

Just like you did. Furthermore your above example works for me. So,
some of the items has no "link" in it or it's null. That's what the
error message means.
