Learning Clojure : unable to fix

I was following a blog post on some sample clojure rest api code and found this -> https://blog.interlinked.org/programming/clojure_rest.html. However, when I try to POST some data using this curl command :-
curl -XPOST -d '{"id": "1", "title": "First document", "text": "First document text"}' http://localhost:3000/documents

, I get the following exception :-

try this:

curl -XPOST -H "Content-Type: application/json" -d '{"id": "1", "title": "First document", "text": "First document text"}' http://localhost:3000/documents
