Clojurians Log v2

I am writing a simple Clojure app https://codeberg.org/injee/injee/src/commit/4efee04b6fb0ccbdf69e89826aa681f9d24b303c/src/injee/api.clj , but I am unable to get post params sent like this:

curl -X POST  \
     -H "Content-Type: application/json" \
     -d '{"key1": "value1", "key2": "value2"}'

If some one can throw light what I am doing wrong, it will be helpful.
