Error Code: 500 Internal Server Error on requesting organization.

Hi,

I implemented Zoho Mail API to authenticate and use zoho mail services.
The problem is when I call the "organization Detail" resource to get the Organization Id I got internal server error. ( checked from server and postman client )

Response: 
" {
    "status": {
        "code": 500,
        "description": "Internal Error"
    },
    "data": {}
}"
