I’m trying to log .info and .warn messages to different files, but all goes to the default file whereas the other is empty.

const infoFileHandler = new log.RotatingFileHandler("INFO", { 
    filename: 'log.log',
    maxBytes: 1024 * 1024 * 10,
    maxBackupCount: 5
});

const warnFileHandler = new log.RotatingFileHandler("WARN", { 
    filename: 'log-warn.log',
    maxBytes: 1024 * 1024 * 10,
    maxBackupCount: 5
});


// Flush every second
setInterval(() => {
    infoFileHandler.flush();
    warnFileHandler.flush();
}, 1000);

log.setup({
    handlers: {
        default: infoFileHandler,
        warn: warnFileHandler
    },
    loggers: {
        info: { level: "INFO", handlers: ["info"] },
        warn: { level: "WARN", handlers: ["warn"] }
    }
})

const logger = log.getLogger();
logger.info("info message");
logger.warn("warning message");

Both files log.log and log-warn.log are created but all messages goes to log.log
