We are using multiple config nodes as part of a flow. Now we have a requirement which allows to pass id of a config node as part of msg.payload which made the config-node field optional. But, if no config node is chosen, a warning triangle is appearing on the node. Is it possible to specify config node is optional?

```auto
 defaults: {
            name: { value: 'WebService' },
            configRef: { type: 'host-details' }
}

```

Yes.

Add `required: false` to `configRef`
