409 Conflict

execution_not_cancellable — Execution not cancellable

Message “Execution is already <status>.”

What causes it

  • The execution is not in `pending`, `running`, or `waiting`; it already completed, failed, or was cancelled. `details[0].message` carries the current status.

How to fix it

  1. Treat the execution as final and read its decision with `GET /executions/{id}`.
  2. To run the applicant again, use `POST /executions/{id}/re_evaluations` or trigger the cascade with a new idempotency key.
