我正在尝试将 Morgan 与 winston 传输和 winston-daily-rotate-file 包集成。我这样做的原因是winston被用于其他一些记录器，我也在尝试使用它。

我正在 ExpressJS 中为 morgan 创建一个流，如下所示：

application.use(morgan(`${process.id} :id [:date[clf]] :remote-addr - :remote-user  ":method :url HTTP/:http-version" :status ":referrer" ":user-agent" :res[content-length] - :response-time ms`,{stream: stream}))

对于正在使用的流，我从 winston 创建了一个像这样的记录器，它每天都会创建一个日志：

let logger = new (winston.Logger)({
                                exitOnError: false,
                                transports: [
                                    new winston.transports.DailyRotateFile({
                                        "filename": './log/access.log',
                                        "datePattern": 'yyyy-MM-dd.',
                                        "prepend": true,
                                        "timestamp": true,
                                        "json": false,
                                        "level": require('../config/domain.conf')['env'] === 'local' ? 'debug' : 'info'
                                    })
                                ]
                        });
        let stream = {
                write: function(message, encoding){
                logger.info(message);
            }
        };

这个问题是有效的。但是日志带有备用行作为空白。这里的逻辑有什么问题，我该如何纠正它。以下是日志的来源：
