Status node not working

General

Hi,
I am not able to get status from Status node. Output is always "undefined".
My nodered flow is as below:

    }
]

Please support on how to get the status. In this example, I am trying to get status of modbus read node, but Status node is not working in general for any node.
Node Red Version: Node-RED v2.2.2

node-red-contrib-modbus version : 5.14.0

Admin edit: added missing ] on the end of the flow, somehow it was missing, which prevented the flow from being imported.

Set your debug node to Output Full Message and have a look at what is in the message.
