Oauth2 Token Request Returns 200 with no payload

I am using the free trial for proof of concept. I am using Postman to aquire an access token. I receive a 200 response from the service but no token is returned; no payload returned in general.

Please note the latest versions of Aspose Cloud APIs uses JSON Web Token(JWT) for authentication. Please check the sample cURL command for this purpose. Hopefully, it will help you to accomplish the task.

# First get Access Token
# Get Customer Key and Customer ID from https://dashboard.aspose.cloud/
curl -X POST "https://api.aspose.cloud/connect/token" 
-d "grant_type=client_credentials&client_id=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx&client_secret=xxxxxxxxxxxxxxxxxxxxxx" 
-H "Content-Type: application/x-www-form-urlencoded" 
-H "Accept: application/json"
