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"`
}

Try setting retries higher than 0. Otherwise assuming stale entries in the registry, in which case you may want to try restart that or clear it out of stale entries, or use the TTL and heartbeat configuration.
