Minimum Working Example

const logger = winston.createLogger({
      levels: winston.config.syslog.levels,
      "info",
    });
    logger.add(new winston.transports.Console());
    logger.format = winston.format.cli();

    logger.log("emergency", "test") // throws "colors[Colorizer.allColors[lookup]] is not a function"

Additional information

it looks like a missing lookup color for emergency syslog level in cli color format.

[Raffaello]

it looks like it also print undefined like a missing variable for these other levels:

  console.log

      notice:undefinedtest
      warning:undefinedtest
      alert:undefinedtest

there is also a warn and warning method, that is not clear which one is right or one is the alias of another.
