dataset_artifact_unavailable

The dataset record exists, but its stored snapshot cannot be read.

dataset_artifact_unavailable is a 409. The dataset row exists and you are authorized to read it, but its durable snapshot could not be read, so nothing can run against it.

The response carries machine-readable recovery in details:

datasetIdThe affected dataset.

Recovery guidance

Re-upload or replace the dataset, then retry the work that needed it. Do not retry the original requestretryable is false because the stored snapshot is missing or unreadable, and no amount of waiting rebuilds it.

Create a new upload for the same source data through dataset uploads and point subsequent runs at the dataset it produces. Automated clients should branch on details.suggestedAction rather than on the message text.
