Hi @sita_ram
I see your configuration looks good. Only thing is you do not have to add group_id in your account schema if all your API requires group_name. Coming to entitlement schema make sure you make group_name as entitlement Id.
I would recommend you to read below resolved post, please follow the steps provided. Do not go by the heading of the topic.
As if you make the configuration as suggested in the post then this issue will be resolved.
