os.Exit(1) is missing here.
also when running the example i run into this error here:
Error when calling GetApplicationLogs: instance is required and must be specified
Did the updated example run for you or could this be related to my environment?

Fixed. I tested the examples with an outdated version of the API.
I also commented the error state in the createOrUpdateApplication waiter because of an internal behaviour of our operator and Kubernetes. We are working on a workaround to solve it, but we would like to merge this and open a new PR with this fix to unlock other tasks that depends on merging and releasing the first version of the sdk.
