The inject node can only set the payload data. In order to alter the msg data, you need to add a change node after the inject node and set the msg.data attribute to what you would like it to be. Then the change node should connect to the node you originally intended to inject into. In your example it would be the debug node. inject -> change -> debug

Hi, i tried what you did, attaching an inject timestamp to a debug node but nothing displayed in the debug window. What could be the possible problem for this? Thanks.
