The failure could be due to network issues, node failure, or insufficient permissions. To resolve this, you can try to manually delete the PITs, ensure the node is running properly, check network connectivity, or verify the user has the necessary permissions to delete PITs. If the issue persists, consider checking the OpenSearch logs for more detailed error information.
