Hello All,  
I have created a custom node and I have deployed it successfully it is working fine but now I have some done some changes in my node.js code and I have replaced my previous custom node code with this code but now it is throwing some error

								console.log('Socket is closed. Reconnect will be attempted in 30 second.', e.reason);
								setTimeout(function() {
									console.log("onclose ----ws reconnect"+ws.reconnect)
									if(ws.reconnect){
										console.log("inside if reconnect")
									connect(ws.index);

							  };

							  ws.onerror = function(err) {
								console.error('Socket encountered error: ', err.message, 'Closing socket');
								ws.close();
							  };
							 if(global.websocket==null || global.websocket==undefined){
								 global.websocket={};

								 global.websocket[urls[i]]=ws;
							 }
							 else{
								 global.websocket[urls[i]]=ws;
							 }
							}
							connect();
							
							}
			
			}
			
		
        });
    }
    RED.nodes.registerType("custom-websocketlistener",CustomWebSocketListener);
}

```

The above code is what I have changed
