I am getting an error like GraphQLError: Unknown operation named "..."

I've noticed the object passed to the GraphQL server consists of:

{
    operationName: "...",
    query: "...",
    variables: { ... }
}

why operationName is passed when it should only send query and variables?

@teckays You can refer to GraphQL Docs http://graphql.org/learn/queries/#operation-name

The operation name is a meaningful and explicit name for your operation.
