JSON Encode models

Hi,

I've been implementing the v2.2 version of the msgraph-sdk this week; however I'm facing an issue.
How can I encode the models returned from the client to JSON so it contains all values? It seems the actual values are in the BackingStore, but how can I make sure I get the actual data to be passed in a response?

For e.g. this works; but doesn't feel as the right solution:

json_encode($event->getBackingStore()->enumerate());

For reference, this is my code example below;

$requestConfig = new CalendarViewRequestBuilderGetRequestConfiguration(
    headers: [
        'Prefer' => 'outlook.timezone="W. Europe Standard Time"',
    ],
    queryParameters: CalendarViewRequestBuilderGetRequestConfiguration::createQueryParameters(
        endDateTime: $endDate,
        startDateTime: $startDate,
        top: 500
    )
);

$events = $this->graphClient
    ->users()
    ->byUserId($userId)
    ->calendar()
    ->calendarView()
    ->get($requestConfig)
    ->wait()
;

foreach ($events->getValue() as $event) {
        // I want to get the complete object as JSON values to be passed in a response
        json_encode($event->getBackingStore()->enumerate());
}

Thank you in advance

The issue names the PHP SDK models and their BackingStore, but no source file, entry point, or test. Start by locating the model serialization and JSON handling, then confirm the expected complete-object output and add or update coverage; the issue does not define acceptance criteria.
