Node and ampq plugin: /amqp/amqp.js:1229 this.channels[channel] = exchange; ^ TypeError: Cannot set property '1' of undefined

This is the error I got initially:

 /home/repo/404hound/node_modules/amqp/amqp.js:1229 

  this.channels[channel] = exchange; 

              ^ 

 TypeError: Cannot set property '1' of undefined  

The solution is to wait until the connection is ready before invoking any start functions:

   var conn = createConnection(); 

   conn.on('ready', function () { 

     conn.exchange(config.exchangeName, function (exchange) { 

       console.log("Starting..."); 

       conn.queue(config.queueName, {durable:true, exclusive:true}, 

         function (q) { 

           q.bind(config.exchangeName, '#'); //subscribe to all messages. 

           q.subscribe(function (msg) { 

             console.log(msg); 

           }); 

         }); 

     }); 

   });
