node.js - winston postgresql 自定义 sql/tableName 不工作

Question

const logger = new (winston.Logger)({
  transports : [
    new winston.transports.PostgreSQL({
      connString :   'xxxxxxxxxxx',
      schema : 'public',
      //tableName : 'logEntry',
      customSql:'INSERT INTO public."logEntry"(logLevel, msg, meta) VALUES ($1, $2, $3);',
    })
  ];
});

数据未插入表中，我在控制台中收到警告:

Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

谁能告诉我这段代码有什么问题？

您需要定义一个错误处理程序来克服此错误消息，

logger.transports.PostgreSQL.on('error', err => 
    console.log('Error while inserting data')
); 

希望这对您有所帮助!
