Hello again,  
I am looking for a way of accessing global/flow variables inside nodes (such as inside the URL of an http-request-node). So I used a change-node to set `global.test` but it remains "undefined" when I try to access it using `{{global.test}}`, even though it is accessible using `global.get("test")`. It seems like the dot notation is not working within the mustache notation, because `{{payload}}` works, while `{{msg.payload}}` doenst. I am quite confused here, please tell me how to access those global/flow variables inside the URL field of a http-request-node, because `{{global.test}}` doenst work for me.

Thanks in advance 🙂

The HTTP Request node does not support accessing flow/global context directly from its url field - it can only access msg properties using the `{{payload}}` syntax.

You would have to build the URL using a Change node before hand as pass it in as `msg.url`.
