What is the shape of `headers`? It looks like headers is a sequence of
two-element sequences, in which case `reformat-headers` should be
something like this -
(defn reformat-headers
[headers]
(map (fn [[x y]] (hash-map [x 0] (.toString [y 1]))) headers))
;; note the destructuring.
The problem is, the lambda inside the map is expecting two args but is
getting one arg (which is a two element sequence) instead.
Hope that helps.
