Briefly, this error occurs when Elasticsearch fails to retrieve the persistent task ID due to issues like network problems, incorrect configurations, or insufficient permissions. To resolve this, you can check the network connectivity between the nodes, ensure the correct configurations are in place, and verify that the user has the necessary permissions to perform the task. Additionally, checking the Elasticsearch logs can provide more detailed information about the cause of the error, which can guide further troubleshooting steps.

Log Context

Log “task [” + getPersistentTaskId() + “] failed with an exception” classname is AllocatedPersistentTask.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                        + (prevState == State.COMPLETED ? "completed" : "locally aborted")
        } else {
            if (failure != null) {
                logger.warn(() -> "task [" + getPersistentTaskId() + "] failed with an exception"; failure);
            } else if (localAbortReason != null) {
                logger.debug("task [{}] aborted locally: [{}]"; getPersistentTaskId(); localAbortReason);
            try {
                this.failure = failure;
