Cursor, Datetime, Node missing?

Sorry this may not be a bug… are these supposed to be there? they don’t seem like “custom” types

Caused by: graphql.schema.idl.errors.SchemaProblem: errors=[There is no scalar implementation for the named  'Cursor' scalar type, There is no scalar implementation for the named  'Datetime' scalar type, There is no type resolver defined for interface / union 'Node' type]

oh nvm, that exception is coming from apollo, still that documentation could be clearer… I presume this is the actual right way to do it.

    GraphQLSchema schema( @Value( "classpath:schema.graphqls" ) Reader schema ) {
        TypeDefinitionRegistry typeDefs = new SchemaParser().parse( schema );
        RuntimeWiring wiring
                = RuntimeWiring.newRuntimeWiring()
                .scalar( ExtendedScalars.newAliasedScalar( "Datetime" )
                        .aliasedScalar( ExtendedScalars.DateTime ).build() )
                .build();
        return new SchemaGenerator().makeExecutableSchema( typeDefs, wiring );
    }

note, I don’t see that the documentation for either clearly explain how to add a value from the extended library, which is presumably different/simpler. Note the exception I mentioned above, doesn’t happen until runtime…
