Undefined is not an object _expo.camera.constant

[Stophface]

I created a RN project with create-react-native-app (CRNA). I want to use the Camera API provided by expo. In doing so, I simply copied the example here https://docs.expo.io/versions/latest/sdk/camera.html and included the Component. Starting the App gives me the following: Undefined is not an object _expo.camera.constant with a massive stacktrace... Any ideas what is going wrong here?
