transports.File not writing to file

I know this was already asked, several times, but either there was no fix, or it just got closed.

$ npm -v 4.4.4

winston: 2.3.1

My logger:

const winston = require('winston');

var logger = new (winston.Logger)({
  /*level: 'error',*/                    // doesn't make a difference
  exitOnError: true,
  transports: [
    new (winston.transports.File)({
      filename: __dirname + '/error.log',
      level: 'error',
      handleExceptions: true,
      humanReadableUnhandledException: true,
      json: true
    }),
    new (winston.transports.Console)()
  ]
});

The console transport works fine when calling e.g.

logger.log('error', 'some message', trace);

But the file transport refuses to work. It doesn’t matter if the file exists or not. It worked fine when I used the default logger winston.log('error', 'bla', someThing);. I also invoke the onLogging event:

logger.on('logging', (transport, level, msg, meta) => {
  if(level === 'error' || level === 'warn'){
    // tell the user that something went wrong.
  }
});

I don’t recall, but I remember running into an issue where the file and/or directory didn’t exist already. Winston won’t create the directory for you, it needs to already exist.

@mhawila nope, wrote my own logger.
