Hello @Drewdrops, welcome to the forum.
Can you put a debug node to show the data coming from Watson?
Set it to display the complete msg, so we can see the values of msg.chatId and msg.payload.

I have attached a debug to the Watson node. Getting this
object
output: object
intents: array[1]
0: object
intent: "Howdy"
confidence: 1
skill: "main skill"
entities: array[0]
generic: array[1]
0: object
response\_type: "text"
text: "Howdy"

please use the "copy value" button when copying a msg or its payload
Also, use the forum `` code button BEFORE pasting the copied value.
What you have pasted is unusable.

This is not a valid path (given your data)
The safest way to determine the path to an item is to use the built in tools - in this case, "copy path"
That results in : `msg.payload.output.generic[0].text`
