Do any one have idea about this exception? Or any one experienced the same issue?
Group Subscription is not a standard object. I read to this doc https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_classes_exception_methods.htm
it says RequiredFeatureMissing A Chatter feature is required for code that has been deployed to an organization that does not have Chatter enabled.
The error is coming in production (Unlimited Edition) but not in the full sandbox.
Also the chatter is enabled.
