Usage Notes
You can only invoke the pub.graphql:load and pub.graphql:loadMany services from a data resolver service and always as a last step.
From a data resolver service, you can invoke the pub.graphql:load and pub.graphql:loadMany services only once.
You can either use a Dataloader or a resolver service to load data. If you are using a Dataloader to load data for a field, then you cannot use the resolver service to load data for the same field. Resolver service should be used only to identify and map the key(s) to pub.graphql:load or pub.graphql:loadMany service.
