Hi i got a strange error. And i think it might be in the package?

I cant authorize my tokens.

My current code -> https://gist.github.com/Tjoosten/b1f691bb0b9b4e8be1fce9c7c49166af

I think is will help other,

check the client_id and client_secret on databases, which is not belong to any user.

I have tried different ways, in the end I notice that my config cache is old and I use this code and my problem solved

php artisan config:clear
