Skip to main content

Hi,


I am trying to add an INSTANCE_SWAP property to a component and I’ve tried with both InstanceNode and ComponentSetNode and I get the same error, listed below.


I am passing the ID of the an InstanceNode that I appended to a frame inside the component to which I attach the property.


What kind of node does it need to be?

Can/must the node be a child of the component?


InstanceNode

Many thanks!

I figured it out. The INSTANCE_SWAP property required the id of a ComponentNode or a ComponentSetNode of the instance you are attaching it to:


const newComponent = figma.createComponent();

const instance = componentSetNode.defaultVariant.createInstance();



newComponent.appendChild(instance);

instance.componentPropertyReferences = {

  mainComponent: newComponent.addComponentProperty(

    "PropertyName",

    "INSTANCE_SWAP",

    componentSetNode.defaultVariant.id

  ),

};



// if you start from an instance and do not have access to its original ComponentNode:

newComponent.appendChild(instance);

instance.componentPropertyReferences = {

  mainComponent: newComponent.addComponentProperty(

    "PropertyName",

    "INSTANCE_SWAP",

    instance.mainComponent.id

  ),

};
