409 List has in-flight sequences

Deleting this list would strand sequences that are mid-cadence: the list disappears while its prospects keep receiving later steps.

Retry only after changing the request

What causes it

• One or more sequences on the list are still running.

How to fix it

• Retry with `?force=true` to pause those sequences first, or pause them yourself and retry. `detail` reports how many are in flight.

`type` is stable and safe to branch on in code. `detail` is specific to your request and is the field to read for the particulars; its wording may change.
