Uncaught Error: BLE HID not enabled

Here's the code:

var controls = require("ble_hid_controls");
NRF.setServices(undefined, { hid : controls.report });

NRF.on('connect',()=>{
  digitalPulse(LED2,1,1000);
});
NRF.on('disconnect',()=>{
  digitalPulse(LED1,1,1000);
  NRF.connect();
  return;
});

var tempTimer = 0;
var timerID = null;
console.log("Battery : "+Puck.getBatteryPercentage()+"%");
var init_mag = Puck.mag();
var cur_mag,last_mag,IntervalID,offset_ang,volumeChanged;
function cal_ang(xyz){
  xyz.x -= init_mag.x;
  xyz.y -= init_mag.y;
  xyz.z -= init_mag.z;
  return (Math.atan2(xyz.y, xyz.x) * 180) / Math.PI;
}
var cur_ang = cal_ang(Puck.mag());
var last_ang = cur_ang;
setWatch(function() {
   digitalWrite(LED3,1);
  start_mag();
}, BTN, {edge:"rising", debounce:10, repeat:true});
setWatch(function() {
  stop_mag();
  if(volumeChanged === null){
    onBtnTap();
  }
  all_lights_off();
}, BTN, {edge:"falling", debounce:10, repeat:true});
function start_mag(){
  volumeChanged = null;
  IntervalID = setInterval(function () {
    cur_ang = cal_ang(Puck.mag());
    offset_ang = cur_ang - last_ang;
    if(Math.abs(offset_ang) > 3 && Math.abs(offset_ang) <45){
      if(offset_ang < 0){
        console.log(" - :" + offset_ang);
        controls.volumeDown();
      }else{
        console.log(" + :" + offset_ang);
        controls.volumeUp();
      }
      last_ang = cur_ang;
      volumeChanged = 5;
      all_lights_off();
      digitalWrite(LED2,1);
    }else if(Math.abs(offset_ang) > 45){
      last_ang = cur_ang;
    }
  }, 500);
}

  timerID = setTimeout(function () {

      controls.playpause();
    }else if(tempTimer == 2){
      controls.next();
      console.log("next");
    }else if(tempTimer >= 3){
      controls.prev();
      console.log("prev");
    }
    tempTimer = 0;
    timerID = null;
                          
  }, 500);
}
function all_lights_off(){
   digitalWrite(LED1,0);
   digitalWrite(LED2,0);
   digitalWrite(LED3,0);
}

//process.on('uncaughtException', function() {
//  digitalWrite(LED1,1);
//  load();
//});

After looking at lots of examples, I thought it should be put at the top. But perhaps that's the wrong place.

Here's the full error I'm getting now:
