call Requset Timeout with detail <nil>

[kanrin]

I'll call a client, but occasionally the request times out, but the information in the detail is
my log
Retrying request. Previous attempt failed with: {"id":"go.micro.client","code":408,"detail":"\u003cnil\u003e","status":"Request Timeout"}
This doesn't happen often, but it does happen occasionally

use go-micro
"go-micro.dev/v4"

and client code

func Call(ctx context.Context, service *ServiceName, endpoint string, req any) error {
	c := client.NewClient(client.WithLogger(NewRpcLog()))
	if !service.Valid() {
		return fmt.Errorf("no valid service: %+v", service)
	}
	s, err := RandomGetService(service)
	if err != nil {
		return fmt.Errorf("get service error: %s", err)
	}
	rsp := new(message.Empty)
	if err := c.Call(ctx, c.NewRequest(s.Name, endpoint, req), rsp, client.WithRetries(0), client.WithRequestTimeout(time.Minute)); err != nil {
		return fmt.Errorf("call client:%s error:%s", s.Name, err)
	}
	if rsp.Count != 1 {
		klog.Debugf("rsp:%+v", rsp)
		return nil
	}
	return nil
}

empty struct such as

type Empty struct {
	Count int `json:"count"`
}
