  title: Amazon Elastic Transcoder Find a Submitted Job by Status and Cancel It
  summary: List jobs that are still in the Submitted state, then cancel the first one returned.
  description: >-
    A clean-up flow that drains pending work. The workflow lists every job
    across the account that currently has a status of Submitted, and when at
    least one is found it cancels the first job in the list. Because only
    Submitted jobs can be cancelled, listing by that exact status guarantees the
    cancel is valid. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
