我使用winston elasticsearch将日志推送到一个elasticsearch集群中。
我已经为我的节点应用程序生成了自签名证书，下面是它的代码。

import * as winston from 'winston';
import * as fs from 'fs';
import { ElasticsearchTransport} from 'winston-elasticsearch';

const esTransportOpts = {

  level: 'info',
  index: 'someIndex', 
  ssl: { 
      ca: [fs.readFileSync('./src/utils/server.cert'), fs.readFileSync('./src/utils/server.key')],
      // This ensures that certificates that are not signed by the 'ca' above get rejected
      rejectUnauthorized: false
        },
  clientOpts: {
    node: process.env.ELASTICSEARCH_URLS,// TODO: Make Variable. 
    // ssl: 'true'
  } 
};
const esTransport = new ElasticsearchTransport(esTransportOpts);
const logger = winston.createLogger({

  transports: [
    esTransport
  ]
});
// Compulsory error handling
logger.on('error', (error) => {
  console.error('Error caught', error);
});
esTransport.on('warning', (error) => {
  console.error('Error caught', error);
});

export default logger;

不幸的是，控制台在尝试推送日志时出现以下错误：

我将感谢任何关于如何解决这个问题的观点。
