Hello!  
I am getting array of the objects at the output. I am able to access elements of zero but unable to access member of the object. I am trying to get minvalue and maxvalue from that object.

Please help me with this!

Sorry But could you help me bit more? I wrote as below. It's not giving me any value.

```auto
let one =msg.payload[0].Agg1_Total_Weight.maxvalue;
msg.payload = one;
return msg;

```

Please paste a flow that demonstrates the issue, for example an inject node that produces a sample message, your function node, and a debug node that shows the wrong/missing data. (You can easily copy a whole message object from a debug node in the debug page.)

Edit: it's hard to see, but you have no msg.payload. The entire message object is an array (bad practice). So it would be `msg[0].Agg1_Total_Weight.maxvalue`, but you should really fix the producer of the msg.

The message does not live in msg.payload. Where does the message come from.  
Make sure to [go through the documentation](https://nodered.org/docs/user-guide/messages) to access elements in an object/array.

You pasted your flow above, but it has the read aggregate node, which I don't have. You need to copy the message going into your function node and paste that here... Ideally with your function node code as well.

Read aggregate node's output going into function node is as below ...

[{"Agg1\_Total\_Weight":{"firsttime":"2022-12-01T03:57:49.743Z","average":3180098.7095534313,"countuncertain":0,"maxvalue":3976252.5,"firstvalue":2368975.8,"countbad":928,"mintime":"2022-12-01T03:57:49.743Z","lastvalue":3976252.5,"sum":48566467492.3,"minvalue":2368975.8,"maxtime":"2022-12-28T03:57:19.256Z","sd":472867.36424514063,"lasttime":"2022-12-28T03:57:19.256Z","countgood":15272},"starttime":"2022-11-30T23:00:00Z","endtime":"2022-12-31T23:00:00Z"}]

Function node:  
What I have written before

```auto
let one= msg.payload[0];
msg.payload= one.maxvalue;
return msg;

```

Then edited

```auto
let one =msg.payload[0].Agg1_Total_Weight.maxvalue;
msg.payload = one;
return msg;

```

anyone of two is not giving any value.

then

```auto
let one =msg[0].Agg1_Total_Weight.maxvalue;
msg.payload = one;
return msg;

```

which is giving error...  
Error: Cannot read properties of undefined (reading 'Agg1\_Total\_Weight')

Haha, this is actually difficult to reproduce 'cause Node-RED is doing everything it can to prevent sending a msg that is an array... That read-aggregate node is pretty messed-up...

Try this: In the function node, add as first line:

```auto
node.warn(msg)

```

and then screen shot or paste what you get in the debug pane.

The other thing I have tried is as below.  
Output of the read aggregate node in function node and in function node written as below..

```auto
let one =msg.payload[0];
msg.payload = one;
return msg;

```

Then output of the function node in split node.Which is giving me 3 parts as below  
1:

In this case you have a payload... It seems you're trying so many combinations so fast that you're getting wires crossed...  
Just put a function node after the read aggregate value and put the node.warn from above in the very first line, and then paste a screen shot of the result in the debug pane here...

Hmmmm, when I put `node.warn(msg)` as first line into a function node I get something looking quite different:

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/0/30d5a326f9631cdad1414c6ca834b485052a4939.png)

Notice how it says "function: (warn)" in the second line in red...

Yes, but somehow, I am not getting message as yours.

hmmm, maybe that requires a setting, I forget. Try `node.error(msg)` instead.

Excellent, so there's a payload in that msg. Now comment out the first line with the node.error() and put in the second line:

```auto
return { payload: msg.payload[0].Agg1_Total_Weight.minvalue }

```

Then add a debug node behind the function node and you should see 2368975.8 appear...
