just the modified data should go to the response. the file should be the original request, with the response

> Ok... You're referring to HTTP Request (that is a Node) - hence my confusion crazy_face (but I didn't have a look at the flow to be fair - so that is on me) Directly after the HTTP IN node Use a change node to store msg.payload in msg.original (use deep clone) After you make changes to payload (for the client) Respond (to client) Then to store the original incoming data, and response to a file (after you respond) use something like below const Log = { request: msg.original, res…

👆  
But in your attempt, you're setting the `payload` to `backup` in the `change` node

Please supply examples as asked for, so there is no ambiguity.

When you send data:0 to the in node

what object should the response get, and what object should the file get.

eg  
file

```auto
{
  "data":0,
  "body":{ 
    "sourceSummary":1,
    "errorNumbers":"errorNumbers",
    "missingNumbers":"missingNumbers"
  }
}

```

Response

```auto
{
  "data":1
}

```

Then it is clear to all

[edit]

I think you would do better with to oupts also  
e.g.

```auto
[{"id":"fa6e50458ab28f21","type":"http in","z":"667cec54c048503c","name":"","url":"/t","method":"post","upload":true,"swaggerDoc":"","x":510,"y":1880,"wires":[["ba1ab5782646f971"]]},{"id":"ba1ab5782646f971","type":"function","z":"667cec54c048503c","name":"store todo in todolist ","func":"let msgfile = {payload: RED.util.cloneMessage(msg.payload)}; // clone payload so no referencing and no res, req object\n\nlet something = {};\nsomething.data = msg.payload.data + 1\n\n// update file object\nmsgfile.payload.body = {\n sourceSummary: something.data,\n errorNumbers: \"errorNumbers\",\n missingNumbers: \"missingNumbers\"\n};\nmsg.payload.data = something.data; // set response payload to ne figure\n\nreturn [msg, msgfile]; //return the two objects to separte outputs","outputs":2,"timeout":0,"noerr":0,"initialize":"","finalize":"","libs":[],"x":680,"y":1880,"wires":[["4a02c0966170e3fc","79597d782ee66032"],["76545b5b7e680c59"]]},{"id":"4a02c0966170e3fc","type":"http response","z":"667cec54c048503c","name":"","statusCode":"201","headers":{},"x":920,"y":1860,"wires":[]},{"id":"79597d782ee66032","type":"debug","z":"667cec54c048503c","name":"res","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":890,"y":1800,"wires":[]},{"id":"76545b5b7e680c59","type":"debug","z":"667cec54c048503c","name":"file","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","statusVal":"","statusType":"auto","x":890,"y":1920,"wires":[]}]

Wow I sure feel stupid. I was a sleep bit deprived and my mind was thinking you get something in and you get something out and I wanted to end on the thing I wanted out. That got me fixed thanks for the help.
