    /**
     * Executes graphql query.
     *
     * More sophisticated Automattic\WooCommerce\Vendor\GraphQL servers, such as those which persist queries,
     * may wish to separate the validation and execution phases to a static time
     * tooling step, and a server runtime step.
     *
     * Available options:
     *
     * schema:
     *    The Automattic\WooCommerce\Vendor\GraphQL type system to use when validating and executing a query.
     * source:
     *    A Automattic\WooCommerce\Vendor\GraphQL language formatted string representing the requested operation.
     * rootValue:
     *    The value provided as the first argument to resolver functions on the top
     *    level type (e.g. the query object type).
     * contextValue:
     *    The context value is provided as an argument to resolver functions after
     *    field arguments. It is used to pass shared information useful at any point
     *    during executing this query, for example the currently logged in user and
     *    connections to databases or other services.
     *    If the passed object implements the `ScopedContext` interface,
     *    its `clone()` method will be called before passing the context down to a field.
     *    This allows passing information to child fields in the query tree without affecting sibling or parent fields.
     * variableValues:
     *    A mapping of variable name to runtime value to use for all variables
     *    defined in the requestString.
     * operationName:
     *    The name of the operation to use if requestString contains multiple
     *    possible operations. Can be omitted if requestString contains only
     *    one operation.
     * fieldResolver:
     *    A resolver function to use when one is not provided by the schema.
     *    If not provided, the default field resolver is used (which looks for a
     *    value on the source value with the field's name).
     * validationRules:
     *    A set of rules for query validation step. Default value is all available rules.
     *    Empty array would allow to skip query validation (may be convenient for persisted
     *    queries which are validated before persisting and assumed valid during execution)
