Queation/Bug: getting “Sending beaconsDidRange with no listeners registered.”

[oferRounds]

I followed the example as is, and everything worked great.

But suddenly, I stopped getting the Beacons detection event, while getting the warning:
“Sending beaconsDidRange with no listeners registered.”

Any idea what might cause this? I’ve tried everything...

I do have the code part:

var subscription = DeviceEventEmitter.addListener(
  'beaconsDidRange',
  (data) => {
       console.log(data);
  }
);
