VladaZakharova opened a new pull request, #75968:
URL: https://github.com/apache/airflow/pull/75968
Vertex AI reports a batch prediction job as JOB_STATE_SUCCEEDED even when
all input rows fail prediction: every row goes to the errors output and no
predictions output is created. CreateBatchPredictionJobOperator only looked at
the job state, so the task succeeded silently and the failure surfaced later in
downstream tasks that expected the predictions table.
The operator now checks the job's completion stats in both regular and
deferrable mode and fails when no row succeeded and at least one failed.
fail_on_empty_predictions=False keeps the previous behavior.
