If (map find-records query-parts) is returning this expression:

(({:a2p-id "1", :dh-uuid "abc-def-ghi-klm"} {:a2p-id "2", :dh-uuid
"def-ghi-klm-opq"} {:a2p-id "3", :dh-uuid nil}) ({:a2p-id "1", :dh-uuid
"abc-def-ghi-klm"} {:a2p-id "2", :dh-uuid "def-ghi-klm-opq"} {:a2p-id "3",
:dh-uuid nil}))

then especially note the double parentheses.  That is a list (or sequence),
whose first element is a list (or sequence) of maps.  You can use (first
(map find-records query-parts)) to get the inner list.
