About this blueprint
CLI
This flow demonstrates how to use the AllowFailure task to allow a task to fail without blocking downstream tasks.
The AllowFailure task is useful if you don't want to block downstream tasks when a specific task fails.
In this example, the task fail_silently will fail, but the flow will continue to run and the task print_to_console will run.
The task will_never_run will never run because the task fail will block downstream tasks after failure.
