I'm using the create_audience_group() method, which is supposed to return a CreateAudienceGroupResponse object. However, in my implementation, it returns None. I verified that the audience group was successfully created by using get_audience_groups(). Additionally, when I called LINE's native API directly, it returned the expected response, but when using the SDK, there is no return value.
