That is not enough info to help you.

Where do you see this?

What was the value of `msg.payload` BEFORE the function node?  
What was does the full `msg` object look like AFTER the function node?

</div>

```auto
// **msg.payload before the function node** 
var name = msg.payload;
name = name[0]["TEMPERATURE"];
msg.payload =name;
msg.payload = msg.payload.toString();
msg.topic = null;

return msg;

```

I have attached a screenshot which you can see the output.

Thank you in advance.

That is your function code - not the value of `msg.payload`

Put a debug BEFORE the function node, show us the value of `msg.payload` before it enters the function

AND a debug AFTER the function node so we can see the FULL `msg` object (set debug node to show complete message)

Ok, one last time

Add debug nodes like this...

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/7/a790328c5340be8b4d5b985efc7553b7c00934ef.png)

... and give them all names (like "Debug Split Func", "debug request func", "debug http response")

Show use what you get out of all three debug nodes.

This is after the function node:

`<str val="undefined" />`

then the incoming payload is not correct. Do as I asked in previous post (add 3 debugs)

Thank you.

I have attached. please see it.

</div>

very odd.

2 things...

1. Copy all the code you have inside the "request\_FromNiagra" function **as it is right now** & paste into a reply (remember ````` formatting)
2. Add `node.warn(["msg.payload", msg.payload, typeof msg.payload])` at the TOP of the "request\_FromNiagra" function and try again

show use what you see in the debug sidebar.

You still have an error because you DID NOT use [the function code I wrote](https://discourse.nodered.org/t/regarding-to-send-a-message-from-node-red-to-niagara-4-framework/58603/20) for you.
