Briefly, this error occurs when OpenSearch tries to update the status of a task that doesn’t exist or has already been completed and removed. This could be due to a timing issue, where the task has finished before the status update was attempted. To resolve this, you could ensure that status updates are only attempted on active tasks. Alternatively, you could handle this error in your application, ignoring it if the task was expected to be short-lived, or logging it for investigation if the task should have still been active.
