We are using Autolaunched Flows, many of which include Pauses of several days. Because of the Pauses, many Flows are throwing errors because the Objects that triggered them (via Process Builder) get deleted. In most instances these were test objects and were purposefully deleted.
What is the best way in a Flow to detect if an object has been deleted? (Or, even better, is there a way to automatically delete related Flow interviews when an object is deleted?)
