Cant set variable by logger.With

[xiaoke4869]

This is my code，and I want to set trace_id into log file. The trace_id is generate on middleware

func NewZapLog(logFileName, traceId string) *zap.Logger {
	encoder := zapcore.NewConsoleEncoder(ZapLogEncoderConfig())
	writeSync := zapcore.AddSync(&lumberjack.Logger{
		Filename:   logFileName,
		MaxSize:    10,
		MaxBackups: 5,
		MaxAge:     30,
		Compress:   false,
	})
	core := zapcore.NewCore(encoder, writeSync, zap.DebugLevel)

	fmt.Printf("NewZapLog traceId %#+v", traceId) // here has value
	sugarLogger := zap.New(core, zap.AddCaller()).With(zap.String("traceId", traceId)) // can not set value

	return sugarLogger
}

The result is:
console output:

NewZapLog traceId "007172A9-038E-4342-8900-FF60C6536F97"

BUT, zap.log didn't write traceId:
log file:

2024-02-01 16:50:20.494321000	INFO	controllers/user_controller.go:153	[Into Controller]	{"traceId": ""}
2024-02-01 16:50:20.494799000	INFO	services/user_service.go:169	[Into UserService]	{"traceId": ""}

Strangely enough

sugarLogger := zap.New(core, zap.AddCaller()).With(zap.String("traceId","123456"))

log file:

2024-02-01 16:51:52.421135000	INFO	controllers/user_controller.go:153	[Into Controller]	{"traceId": "123456"}
2024-02-01 16:51:52.421301000	INFO	services/user_service.go:169	[Into UserService]	{"traceId": "123456"}

code:

It works... What should I do? Thx.

func init() {
	fmt.Println("===== zap init")
	Log = NewZapLog(viper.GetString("log.zapLogPath"), "init").Sugar()
}

log file always output "init"

2024-02-01 17:01:52.399440000 INFO controllers/user_controller.go:153 [Into Controller]	{"traceId": "init"}
2024-02-01 17:01:52.399575000	INFO services/user_service.go:169 [Into UserService]	{"traceId": "init"}
