Hi, I have a function node which creates a token for use in a http request node.

```auto
let token = flow.get('token');

msg.cookies = {
    'IDALToken=' : token
    }
return msg;

```

Worked flawlessly, up to the update from Node Red 4.0 to 4.0.5. Now I get an error warning:  
`"TypeError: argument name is invalid"`

I suppose this has something to do with [Ensure will payload is a string #4873](https://github.com/node-red/node-red/pull/4873). How should I modify the function node to avoid this error? Thank you!

Hi @Graefe

Sorry - what's the connection between the above (HTTP Looking) snippet and MQTT?  
also, unless its required by the service you're interacting with, the cookie name does not need an `=` after it

```auto
msg.cookies = {
    'IDALToken' : token
}
return msg;

```

Are you sure this error is coming from the above?  
maybe share a flow that reproduces the error?

Yes, this was the solution! No idea, why Node Red prior to 4.0.3 had no problems with this expression.  
The connection is, that there is a http-request node which uses the token as a cookie. And which sent the error - until now. I hope this describes the setup well enough. [Work with cookies : Node-RED](https://cookbook.nodered.org/http/work-with-cookies).  
Thank you!

Awesome!

I have updated the title to represent the Node you had problems with.
