You've registered two handlers for the same event. It is unlikely that the TinyWebServer class manages this.
You should have one handler for each event (POST, GET, PUT, etc.) and, in that handler, deal with all the data passed in.
For instance, the GET request should include information about which LED you want the status of, and the led_status_handler method should get the status of that LED (not a hard-coded number).
