For your sample app to work, you should have a Kontent.ai project containing content. Your app should be then configured with its project ID. You can either get it by signing in using your Kontent.ai credentials or by signing up for a trial. Later, it will be converted to a free plan.
You may wish to either select from existing projects or create a new sample project. The app will be configured with its project ID.
Alternatively, you can configure your app manually by submitting a project ID below.
Alternatively, you may wish to use the shared project (project ID "975bf280-fd91-488c-994c-2f04416e5ee3").
Note: You cannot edit content in the shared project.
