Fills in an assign with a fallback value when it is nil. Pass-through when the assign already has a value. Handy after a best-effort lookup where you want to keep going with a sensible default rather than halting or branching.

​
Configuration

  • Assign — the assign to default.
  • Default source — where the fallback value comes from. Standard Flow Compose vocabulary: Assign, Extract, Dated property, Literal.

​
Tips

  • For a fail-fast pattern instead, use Flow Guard with Bail when: Not set.
