Example not working: Logging not serializing arguments

[basickarl]

Please tell us about your environment:

• _winston version?_3.2.1
  • winston@2
  • [x ] winston@3
• _node -v outputs:_v10.16.0
• Operating System? (Windows, macOS, or Linux) Linux
• Language? (all | TypeScript X.X | ES6/7 | ES5 | Dart) TypeScript 3.4.5

What is the problem?

    const log = createLogger({
        level: logLevel,
        format: format.json(),
        defaultMeta: { service: 'user-service' },
        transports: [
            new transports.File({ filename: 'logs/error.log', level: 'error' }),
            new transports.File({ filename: 'logs/combined.log' })
        ]
    });
        log.add(
            new transports.Console({
                format: format.simple()
            })
        );

Console transport is not serializing the arguments.
Expecting all arguments

What do you expect to happen instead?

According to https://github.com/winstonjs/winston/blob/master/README.md#usage the above states: ${info.level}: ${info.message} JSON.stringify({ ...rest }) instead the following code log.debug('hello', { there: 1 }); results in the following: debug: hello [object Object] {"service":"user-service"}. My Object has not been serialized.

Hmm, I believe the issue I filed, #1933, is related to this. It seems like whenever two or more transports are in use, the first transport listed gets the full info object, but the second transport only receives an info object with Winston "known" properties, i.e. level, message, timestamp, and the [Symbol(splat)] properties.

There is a comment on #1430 which resolves the issue with info "losing data" between transports.
