Hi, I am trying to connect my application to Zoho API using C# SDK but I am getting the following error. It seems like the connection is fine but it is unable to get the data. I have enabled the module.all scope and read scope, for access token, as well.

ZCRM_INTERNAL_ERROR

Object reference not set to an instance of an object.

Here is my code:

1. public static Dictionary<string, string> config = new Dictionary<string, string>()
   

   {
   

       {"client_id","1000.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"},
   

       {"client_secret","xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"},
