The Debug node causes any message to be displayed in the Debug sidebar. By default, it just displays the payload of the message, but it is possible to display the entire message object.

Openning the Debug Tab

1. To toggle the Info & Debug Tabs, click on Click on “≡” in the upper right hand corner of the Canvas then click on “View” → “Show sidebar”.

2. To open the Debug Tab, click on Debug on the right hand corner of the tab.

Hint :You can clear the content of the debug tab by clicking on the red trashcan.

The Debug Node

The Debug outputs the output of the connected node to the Debug Tab.

Hint : This is a great tool to figure out what a node is outputting. Simply connect and watch the node’s output populate the debug node.

3. Add a debug and connect it to the “text” state.
