Having issues with my node RED Code

trying pull information from Watson but getting an error in my function node

CODE:
msg.payload = {

    chatId : msg.chatId,
    type : "message",
    content : msg.payload.output.text[0]

};
return msg;

ERROR:

"TypeError: Cannot read properties of undefined (reading '0')"

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
image

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"
chrome_hspz14YGHn

That results in : msg.payload.output.generic[0].text
