runtime error: invalid memory

[RealLau]

I just encountered a runtime error, the logs is as below:

my code is simple as send a http get request in a every 5min job:

func (e UpdateNews) Run() {
	resp, err := http.Get("https://sample_site.com/common/update_news/")
	if err != nil {
		fmt.Println("Call update news failed")
	}
	var res map[string]interface{}
	json.NewDecoder(resp.Body).Decode(&res)
	resCode := fmt.Sprintf("%v", res["code"])
	if resCode == "0" {
		fmt.Printf("Every 5 mins update news success.")
	}
}
func main(){
jobrunner.Start() // optional: jobrunner.Start(pool int, concurrent int) (10, 1)
	err := jobrunner.Schedule("@every 300s", UpdateNews{})
	if err != nil {
		panic(err)
	}
}

You need to declare UpdateNews{}

type UpdateNews struct {}

Also the error response from jobrunner.Schedule... is related to parsing of cron. Maybe 300s should 5m
