Livechat Oauth not working as expected.

[Iciren93]

Hi, I have been wanting trying to authorize my app as state here
https://developers.livechat.com/docs/authorization/authorizing-api-calls/#step-2-redirect-users-to-livechat-oauth-server-1

But I keep getting error saying missing param or incorrect value. I have already gone through with LiveChat support and it seems like the request I have been making to be correct but not too sure why it is happening and suggested that I raise an issue in github. I am not sure this is the correct place to raise this issue, please let me know if there is another more appropriate place for this.

My request sample(the redirect uri is already whitelisted):
