This exception can be used to allow a task running on an engine to test if the engine (or the user's namespace on the engine) has the needed task dependencies. If not, the task should raise this exception. For the task to be retried on another engine, the task should be created with the `retries` argument > 1. The advantage of this approach over our older properties system is that tasks have full access to the user's namespace on the engines and the properties don't have to be managed or tested by the controller.
