Redis or MySQL cannot be used before the request

[guoxk]

I used the helleim-0.9.9-py310 library and golang 1.18.1 to test. Once I used Redis or MySQL before the request, the program would crash. The following is the request code:

func main() {
	rds := connect.GetRedis()
	defer rds.Close()
	//Get a message from Redis
	str, err := redis.String(rds.Do("rpop",“test_key”))
	if err != nil {
		log.Println(err)
		return
	}
	log.Println(str)
	apiKey := "my_Key"
	helheimClient, err := helheim_go.ProvideClient(apiKey, false, true, nil)
	if err != nil {
		log.Println(err)
		return
	}
	// check possible options in the python examples
	options := helheim_go.CreateSessionOptions{
		Browser: helheim_go.BrowserOptions{
			Browser:  "chrome",
			Mobile:   false,
			Platform: "windows",
		},
		Captcha: helheim_go.CaptchaOptions{
			Provider: "vanaheim",
		},
	}
	session, err := helheimClient.NewSession(options)
	if err != nil {
		log.Println(err)
		return
	}
	reqOpts := helheim_go.RequestOptions{
		Method:  http.MethodGet,
		Url:     "https://www.genx.co.nz/iuam/",
		Options: make(map[string]string),
	}
	resp, err := session.Request(reqOpts)
	if err != nil {
		log.Println(err)
		return
	}
	log.Println(resp.Response.Body)
}

@guoxk
you are right. i can reproduce.

the interesting part is, when you move the helheim client initialization before the redis one it should work.

this part:

apiKey := "my_Key"
	helheimClient, err := helheim_go.ProvideClient(apiKey, false, true, nil)
	if err != nil {
		log.Println(err)
		return
	}

will investigate why this happens
