Clojurians Log v2

i'd like to upload a few files using the multipart/form-data content type, like this: curl -L -X POST '<http://app/upload>' -F '=@mobydick.txt' -F '=@report.pdf' i've added a new route:

["/upload" :post [(io.pedestal.http.ring-middlewares/multipart-params) `upload]]

where upload is just a function that prints the request for now. the :multipart-params is null, however. what am i missing and how can i get the uploaded data?
