Hi Abhishek,
I am trying to generate access token for automatic login using TOTP. But I am getting the following error
{“s”: “error”, “code”: -1018, “message”: “something went wrong”}
I am referring to the same code given in github. Can you please help me in this.

Abhishek, if you can respond in this forum itself it would be really helpful.
When I run the code, totp generation is fine but getting stuck with verify pin result only.
send_login_otp success
generate_totp success
verify_totp_result success
verify_pin_result failure - {“s”: “error”, “code”: -1018, “message”: “something went wrong”}
