Hi!

1. own created node.
2. drop my node to flow
3. set configuration in the field  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/7/76d2aef6b74e15721e5dea1a76fe65b2c418ef9f.png)
4. trying lookup some information based on configuration field  
server: { value: "", type: "hc2-server-config", required: true },  
(ip/login/pwd) via Fibaro Home Center
5. code  
var node = RED.nodes.getNode(req.params.id);  
if (node !== null && typeof node !== "undefined") {

so, if flow with this node is NOT saves - node is NULL  
otherwise OK.

my question is, why I can't start design node at runtime when a node is not saved yet.

thank you!

Sorry, I don't fully follow your question.

Can you provide some more details?

Where are you trying to lookup the information? How are you doing that?

Where is that code?

Hi - I was asking for more explanation, not more code. So I've now had to study you code to figure out what you are asking.

A node does not exist in the runtime until it has been deployed.

If you need the runtime to do something for a node you are still configuring and have not deployed, you'll need to pass all the required information as a part of the HTTP request you make to the runtime.
