Hello!

I use the following code inside a function:

```auto
var url = msg.payload.url;
var urlEncoded = encodeURIComponent(url);
var requestUrl = 'https://opengraph.io/api/1.1/site/' + urlEncoded + '?accept_lang=auto&cache_ok=false&use_proxy=true&app_id=XXX';
msg.payload.requestUrl = requestUrl;
return msg;

```

before calling an api using a http request with

```auto
Method: Get
URL: {{msg.payload.requestUrl}}
Payload: ignore

```

However, I am always presented with an error:

> "No url specified"

although the log shows a requestUrl `https://opengraph.io/api/1.1/site/http%3A%2F%2Fgoogle.com?accept_lang=auto&cache_ok=false&use_proxy=true&app_id=XXX` which works in the terminal. So I guess the error does not appear whilst generating the URL but rather when calling it; any idea how to fix this?

Any help much appreciated!

Hi @chloroquine

I suspect you need to use `{{payload.requestUrl}}` in the URL field - without the `msg` prefix.

However you could also leave that field blank and set the `msg.url` property rather than `msg.payload.requestUrl` - as the node will use that if provided.

Hi @knolleary! Thanks! However:

Using `{{payload.requestUrl}}` leads to the following:

> Error: getaddrinfo ENOTFOUND https : [http://https](http://https)://opengraph.io/api/1.1/site/http%3A%2F%[2Fgoogle.com?accept\_lang](http://2Fgoogle.com?accept_lang)=auto&cache\_ok=false&use\_proxy=true&app\_id=XXX

Changing to msg.url shows:

> Warning: msg properties can no longer override set node properties. See bit.ly/nr-override-msg-props

As Nick says, use the msg.url property instead. Then you can put everything in the function node and leave the url blank in the request.
