Hi Eric,
As part of the Cloud Endpoints Framework 2.0, the JSON-RPC protocol, which is required for legacy iOS clients and automatic kind fields features are not currently available. See Currently excluded features and tools for Cloud Endpoints 2.0 documentation <https://cloud.google.com/appengine/docs/java/endpoints/migrating#currently_excluded_features_and_tools> for more details. In case you require any of these features, migration to Cloud Endpoints 2.0 is currently not recommended. More on the topic of RPC functionality, you may be interested in the Cloud Endpoints for gRPC APIs concepts <https://cloud.google.com/endpoints/docs/grpc> which would serve as the new and faster method for directly calling methods on a server application on a different machine. More details on how to use this new feature are provided on the Configuring a gRPC API Service guide <https://cloud.google.com/endpoints/docs/grpc-service-config>. Note that this is a Beta release of Google Cloud Endpoints. This feature is not covered by any SLA or deprecation policy and may be subject to backward-incompatible changes. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
