Winston 3 Console Transport removing whitespace

I have come across this this while trying out winston 3.

OS: Macos 10.13.4 Terminal: iTerm2 or Terminal.app Winston: 3.0.0-rc5 Node: 8.11.1

I am using a custom formatter that is setting options[Symbol.from('message')] before returning it to winston. I am providing to that transport the following string (an example):

                                   \u001b[36m\u001b[4m*INFO   * ↳ \u001b[24m\u001b[39m     pid:   \u001b[33m13071\u001b[39m

But sometimes both newlines and initial whitespace are being ignored when writing to the console. This doesn’t seem to happen when running on linux.

Here’s what I’m experiencing; maybe its related?

When I don’t use uppercase method on info.level I get logs on console as expected

2018-06-24 00:03:47 [jarvis-server] info: App is running at http://localhost:3000 in development
2018-06-24 00:03:47 [jarvis-server] info:  Press CTRL-C to stop

2018-06-24 00:03:47 [jarvis-server] error: Db already exists

but when I use uppercase method

                                        : App is running at http://localhost:3000 in development
                                        :  Press CTRL-C to stop

                                         : Db already exists

Code (Typescript)

import * as winston from 'winston';

const logFormat = winston.format.printf(info => {
  // return `${info.timestamp} [${info.label}] ${info.level}: ${ info.message }`;
  return `${info.timestamp} [${info.label}] ${info.level.toUpperCase()}: ${
    info.message
  }`;
});

const logger = winston.createLogger({
  level: process.env.LOG_LEVEL,
  transports: [new winston.transports.File({ filename: 'app.log' })],
  format: winston.format.combine(
    winston.format.label({ label: 'jarvis-server' }),
    winston.format.timestamp({ format: 'YYYY-MM-DD HH:mm:ss' }),
    logFormat
  )
});

if (process.env.NODE_ENV !== 'production') {
  logger.add(
    new winston.transports.Console({
      format: winston.format.combine(
        winston.format.colorize(),
        winston.format.label({ label: 'jarvis-server' }),
        winston.format.timestamp({ format: 'YYYY-MM-DD HH:mm:ss' }),
        logFormat
      )
    })
  );
}

export default logger;
