log4js version: log4js@6.9.1

my code is ( logger.ts ):

const config = {
    appenders: {
        debug: {
            type: 'console',
        },
        info: {
            type: 'dateFile',
            filename: 'logs/info',
            pattern: '-yyyy-MM-dd.log',
        },
        //错误日志 type:过滤类型logLevelFilter,将过滤error日志写进指定文件
        errorLog: {
            type: 'dateFile',
            filename: 'logs/error',
            pattern: '-yyyy-MM-dd.log',
        },
        error: { type: 'logLevelFilter', level: 'error', appender: 'errorLog' },
    },
    categories: {
        default: { appenders: ['debug', 'info', 'error'], level: 'debug' },
        info: { appenders: ['info', 'error'], level: 'info' },
    },
};

log4js.configure(config);

export default log4js;
