Format run unattended_blocked: assembled_deliverable is false

unattended_blocked means the run stopped instead of claiming a deliverable it did not make. The harvested media are intermediates, not the cut.

When a Format run ends with output_error.code: "unattended_blocked", the run stopped and did not claim a deliverable it never produced. details.assembled_deliverable is false, and details.harvested counts the media by type. Those media are intermediates, not the completed cut, so do not publish them as the result (Structured output).

Read the receipt

The cause is usually that an unattended run reached a step that needs a person, such as an approval. Sume stops there rather than invent a result.

FieldMeaning
output_error.messageThe reason, in the words of the run.
details.harvestedA count of media by type that the run did make.
details.assembled_deliverablefalse: no finished deliverable exists.

What to do next

If you want to fail fast instead, put the choice in the Format's instructions so no step needs a person.

  • Read message and decide if your input or instruction left a decision open.
  • Answer it in a continuation: previous_run_id plus an instruction that names the decision.
  • Reuse the harvested media in the continuation. They are on the thread and do not need to be made again.
  • Send a new Idempotency-Key and a spend cap with the continuation.
