How to get medias appointment

[JGalbois]

Hi

I am trying to retrieve the media attached to an appointment

	$calendar = $ews->ews->getCalendar();
	$oEventDetail = $calendar->getCalendarItem($ExchangeId, $ChangeKey);
	$attachments = $oEventDetail->getAttachments();

I see clearly 1 media

	tFileAttachment : Array
	(
		[0] => garethp\ews\API\Type\FileAttachmentType Object
			(
				[isContactPhoto] => 
				[content] => 
				[attachmentId] => garethp\ews\API\Type\AttachmentIdType Object
					(
						[rootItemId] => 
						[rootItemChangeKey] => 
						[id] => AAMkADZhNGEwMDM0LTUyYzQtNDY1Ni05YzhjLTk2NWY1NmY4OTA2MABGAAAAAADdQnAC3NjZSoBxMzH8bQlpBwAN5TKg81M8QL8H2m8inmvJAAAE8fPWAAAN5TKg81M8QL8H2m8inmvJAAB4IQvCAAABEgAQABIuYtzxgExAvD23NKSxL8s=
						[_] => 
						[_value] => 
						[_typeMap] => Array
							(
							)

					)

				[name] => titres.PNG
				[contentType] => image/png
				[contentId] => 
				[contentLocation] => 
				[size] => 1889
				[lastModifiedTime] => 2023-07-31T13:10:36
				[_typeMap] => Array
					(
						[lastModifiedTime] => dateTime
					)

				[isInline] => 
				[_] => 
				[_value] => 
			)

	)

I see the media key clearly
$tFileAttachment[0]->getAttachmentId();

Here is my trace

garethp\ews\API\Type\AttachmentIdType Object
	(
		[rootItemId] => 
		[rootItemChangeKey] => 
		[id] => AAMkADZhNGEwMDM0LTUyYzQtNDY1Ni05YzhjLTk2NWY1NmY4OTA2MABGAAAAAADdQnAC3NjZSoBxMzH8bQlpBwAN5TKg81M8QL8H2m8inmvJAAAE8fPWAAAN5TKg81M8QL8H2m8inmvJAAB4IQvCAAABEgAQABIuYtzxgExAvD23NKSxL8s=
		[_] => 
		[_value] => 
		[_typeMap] => Array
			(
			)

	)

But when I try to retrieve the content, I get an error

	$calendar->getAttachment($tFileAttachment[0]->getAttachmentId());
	>> Fatal error: Uncaught Error: Call to undefined method garethp\ews\CalendarAPI::getAttachment()

Do you have an idea how to do this?

Thank's
