'debug' module in handlers

[pafik13]

I try to use debug in handler and it's not working. How to fix it?
Code:

...
const agcBrokerClient = require('agc-broker-client');
const log = require('debug')('asyngular');   // <-- DECLARE

const ENVIRONMENT = process.env.ENV || 'dev';
...
...
...
// Asyngular/WebSocket connection handling loop.
(async () => {
  for await (let {socket} of agServer.listener('connection')) {
    // Handle socket connection.
    console.log('connect', socket);  // <-- work
    log('connect');  // <-- NOT work

    (async () => {
      // Set up a loop to handle remote transmitted events.
      for await (let data of socket.receiver('customRemoteEvent')) {
        console.log('customRemoteEvent', JSON.stringify(data));  // <-- work
        log('customRemoteEvent %o', data);  // <-- NOT work
      }
    })();
  }
})();
...
...

Does it work outside of the async IIFE?
