Login system error

[gampangdibaca]

Im having trouble with login.
I dont know what is username is. coz i have tried pixiv ID, email, and nickname. (nothing works)

here is my login code :
account, err := pixiv.Login("xxx", "xxx") if err != nil { log.Println(err) } fmt.Println(account)

and the message on the console :
2021/06/14 14:26:36 Login system error: Invalid grant_type parameter or parameter missing <nil>

can anyone help me to understand this?
and also if i try to get other user detail without login, i get the message missing refresh token.

Thanks

you can try to get an access/refresh token manually: upbit/pixivpy#158 (comment)
