See that the error is related to dump. How do you use dump?

[imroc]

Is there code to reproduce it?

[JamesSunXX]

fmClient := req.C().
		SetTimeout(time.Second * 3).
		EnableTraceAll().
		SetCommonRetryCount(1)

resp, err := fmClient.R().
		SetBodyJsonMarshal(data).
		EnableDump().
		EnableTrace().
		Post(domain + getToken)
	if err != nil {
		return res, err
	}

	respCode := gjson.Get(resp.String(), "errcode").Int()
	if respCode != 0 {
		logger.ErrLogger().WithFields(logrus.Fields{
			"resp":    resp.Dump(),
		}).Errorf("request invalid resp err")
		return res, requestErr
	}

[imroc]

Can't reproduce in my environment, looking at the stack of panic, the bytes.Buffer of go1.17.9 is out of range when grow().

Has the go standard library used for compilation been modified? Or upgrade the standard library to the latest version and try again.
