task does not have a lifecycle set

Error message

task does not have a lifecycle set

What it means

A lifecycle guard inside defaultDeltaRunMethod: before running the find/compare/render procedure, the task's Lifecycle field must be set (fi.Exists, fi.Ignore, or fi.CreateThenDelete etc.). A nil Lifecycle means the task struct was built without its lifecycle populated — a programming/setup error in the task definition, not a user input problem.

Solutions

1. Set the Lifecycle field when constructing the task (typically from the model builder, e.g. fi.PointerTo(fi.LifecycleExists))
2. Check the task's CompareWith/normalization path did not drop lifecycle during cloning
3. Add a validation in the task's CheckChanges so this surfaces earlier with context
