expressWinston.errorLogger: No logging when using level

[martinzuern]

When using a function for the level option, nothing will be logged by the error logger. Please find a simple example attached:

  app.use(expressWinston.errorLogger({
    winstonInstance: logger,
    msg: '{{err.message}}',
    level: function() {
      return 'warn';
    }
  }));

I just tested this, and it seems to be working fine. Is it possible that you have your transport(s) on your winstonInstance set not to log at the "warn" level?

Here's the code I used (with some transport options laid out as well):

app.use(expressWinston.errorLogger({
  transports: [
      new winston.transports.Console({}),
      // new winston.transports.Console({level: 'warn'}), // also works
      // new winston.transports.Console({level: 'error'}), // DOES NOT work (reproduces bug)
  ],
  msg: '{{err.message}}',
  level: function() {
    return 'warn';
  }
}));

Thanks for your quick response. You're right – sorry for bothering you with this issue.

No problem!
