Hyperledger Composer How to subscribe to and see events from transactions

Question

Code to connect to the Hyperledger Runtime:

const BusinessNetworkConnection = require("composer-client")
  .BusinessNetworkConnection;
this.businessNetworkConnection = new BusinessNetworkConnection();
this.CONNECTION_PROFILE_NAME = "hlfv1";
this.businessNetworkIdentifier = "testNetwork";
this.businessNetworkConnection
  .connect(
    this.CONNECTION_PROFILE_NAME,
    this.businessNetworkIdentifier,
    "admin",
    "adminpwd"
  )
  .then(result => {
    this.businessNetworkDefinition = result;
    console.log("BusinessNetworkConnection: ", result);
  })
  .then(() => {
    // Subscribe to events.
    this.businessNetworkConnection.on("events", events => {
      console.log("**********business event received**********", events);
    });
  })
  // and catch any exceptions that are triggered
  .catch(function(error) {
    throw error;
  });

When I submit transactions and make a request through my generated REST APIs no events are seen by my server. Need help

Answer 1

Here's the problem:

this.businessNetworkConnection.on('events' //This should be changed to the following:

this.businessNetworkConnection.on('event'
