Winston formats screwing things up

[peebles]

The MESSAGE symbol in the info object seems to get messed up when using "formats".

"winston": "^3.0.0"
"winston-syslog": "^2.0.0"

I place a "console.log( info )" right at the top of the log() method. Consider this example with no formats:

const winston = require( 'winston' );
require( 'winston-syslog' );
let log = winston.createLogger({
  transports: [
    new winston.transports.Syslog({
      host: '192.168.99.100',
      port: 514,
      protocol: 'udp4',
      app_name: 'test'
    })
  ]
});


log.info( 'This is a test!!' );
setTimeout( () => {
  process.exit(0);
}, 1000 );

The console.log shows:

{ message: 'This is a test!!',
  level: 'info',
  [Symbol(level)]: 'info',
  [Symbol(message)]: '{"message":"This is a test!!","level":"info"}' }

and that is good. Now consider this example:

const winston = require( 'winston' );
require( 'winston-syslog' );
let log = winston.createLogger({
  format: winston.format.combine(
    winston.format.label({ label: 'right meow!' }),
  ),
  transports: [
    new winston.transports.Syslog({
      host: '192.168.99.100',
      port: 514,
      protocol: 'udp4',
      app_name: 'test'
    })
  ]
});


log.info( 'This is a test!!' );
setTimeout( () => {
  process.exit(0);
}, 1000 );

The console.log now shows:

{ message: 'This is a test!!',
  level: 'info',
  label: 'right meow!',
  [Symbol(level)]: 'info' }

The [Symbol(message)] has disappeared and now "const output = info[MESSAGE];" on line #117 is undefined!

Not sure if this is a problem inside winston or here in syslog.

+1 Seeing the same problem and looks like this issue has not been acknowledged since last year.
