Hey @heejin this looks like an issue with how you have named your page model. You need to change the model name in your integration code. Update BuilderComponent and builder.get call modal name to “test-page”.

Yeah you’re right. Seems like in the app router document sample code (Integrating Sections - Builder.io) the BuilderComponent is missing model props so it’d be better to be updated it for other people. Thanks!
