GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
The GraphQL response should contain id:123 and meta:testing, because the Lambda function is echoing them back. After a few seconds, you should see a record in CloudWatch Logs with these details as well.

annotate() ¶ annotate(*args, **kwargs)¶. Annotates each object in the QuerySet with the provided list of query expressions.An expression may be a simple value, a reference to a field on the model (or any related models), or an aggregate expression (averages, sums, etc.) that has been computed over the objects that are related to the objects in the QuerySet.
Notes Null values: all filtering functions return false when compared with null values. You can use special null-aware functions to write queries that handle null values. isnull(), isnotnull(), isempty(), isnotempty(). Tips. To get the fastest performance: Use simple comparisons between column names and constants.
