Some progress. I’ve added the line {:ok, body, conn} = Plug.Conn.read_body(conn) below
def process(conn, params) do
IO.inspect params, label: "params for 'process'"
{:ok, body, conn} = Plug.Conn.read_body(conn)
IO.inspect body, label: "BODY"
conn |> render("pdf.json", url: "OK")
end
Now I am seeing data:
[ debug] Processing with Koko.Web.PrintController.process/2
