errorLogger is not working

[theromie]

I am using express-routes-mapper for routes and I have expressWinston.logger({}) before app.use('abc/xyz', mappedOpenRoutes); and expressWinston.errorLogger({}) after app.use('abc/xyz', mappedOpenRoutes); but expressWinston.logger({}) showing in console but errorLogger is not showing error into file.
I have error like ReferenceError: email is not defined but that is not being logged.

app.use( expressWinston.errorLogger({ transports: [ new winston.transports.Console(), new DailyRotateFile({ filename: '%DATE%-error.log', datePattern: 'DD-MM-YYYY', maxSize: '20480', zippedArchive: true, }), ], format: winston.format.combine( winston.format.colorize(), winston.format.json() ), msg: '{{err.message}}', }) );

I'm also having this kind of scenario. Any updates on this one? Thanks!

It posts the Errors console, but does not use JSON. So it is always only posting to console.

  app.use(
    // This is not posting as JSON in production
    expressWinston.errorLogger({
      transports: [new winston.transports.Console()],
      format: winston.format.combine(winston.format.json()),
   })
 )
