go-whatsapp: Cant login

error during login: error decoding login resp: json: cannot unmarshal array into Go value of type map[string]interface {}

login successful, session: {uocSvrqQWvColFnkQ0aW2w== [] [] }

go func() {
		terminal := qrcodeTerminal.New()
		terminal.Get(<-qr).Print()     //err here
	}()

I have no session in /tmp, the problem generates when trying to generate QR code. Ive already updated to last version of the repo. Thanks in advance
