Regarding to send a message from Node red to Niagara 4 framework

General
22

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?

23 
// **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)

THis is the before the function node

26

Ok, one last time

Add debug nodes like this...

... 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.

27

This is after the function node:

<str val="undefined" />

28

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

29

Thank you.

I have attached. please see it.

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.

// assign some variables
username = "obixUser";
password = "Wetec123456#@";
ipAddress = "172.30.34.212";
httpsPort = 443;

//create a base64 digest

authHash = Buffer.from(username+":"+password).toString("base64");

//ordSlot = "/Drivers/SysmikScaIoNetwork/AI4_2/points/Ai3/out/value";
ordSlot = "/Supply$20Fan/NewValue";
//ordSlot = "/Supply$20Fan/p";
// create the message for the get request
operation = "/set";
msg={
    "method": "POST",
    "url": "https://"+ipAddress+":"+httpsPort+"/obix/config"+ordSlot+operation,
    "headers":{
        "Authorization": "Basic" + authHash,
        "Accept":"*/*"
    }
    
};

//ignore cert expired error

msg.rejectUnauthorized = false;


//msg.payload = '<str val ="'+msg.payload+'"/>';


msg.payload = `<str val="${msg.payload}" />`;
return msg;

You still have an error because you DID NOT use the function code I wrote for you.

33

Thank you so much.

Now I got the results.

Thank you once again.
