ms graph php sdk message object fails to check if there are attachments

I am retrieving messages from an Outlook account. I am trying to get inline files and attachments from those messages.

$graph = new Graph();
$graph->setAccessToken($this->getAccessToken());

$messageQueryParams = array (
    "\$select" => "subject,receivedDateTime,from,sentDateTime,body,toRecipients,sender,uniqueBody,ccRecipients,bccRecipients,attachments",
    "\$orderby" => "receivedDateTime DESC",
    "\$top" => "200" 
);

$url = '/me/mailfolders/' . $folder . '/messages/delta';
$url_combiner = '?';

$getMessagesUrl = $url . $url_combiner . http_build_query($messageQueryParams);
$response = $graph->createRequest('GET', $getMessagesUrl)->execute();

$messages = $response->getResponseAsObject( \Microsoft\Graph\Model\Message::class );

foreach($messages as $msg) {
     echo $msg->getHasAttachments();
}

This code returns 'null' for $msg->getHasAttachments(); I would expect it to return a true or false.

The messages I am downloading from this folder have both inline attachments and mail attachments, so I am looking for a solution to both.

(Responses that point to specific points in the MS Graph PHP SDK documentation are very appreciated.)

This is the expected behavior, in your case getHasAttachments() method returns null since hasAttachments is not included in $select query option and therefore it is not requested from a server. It needs to be explicitly included, for example:

$messageQueryParams = array (
    "\$select" => "hasAttachments,...",
    //another params are omitted for clarity
);

Then whether a message contains attachments or not could be determined like this:

foreach($messages as $msg) {
    if($msg->getHasAttachments() == true){
        //...
}

There is one more issue with the provided example, to retrieve Message.attachments reference property (or relationship property) it needs to be specified via $expand query string parameter instead of $select (refer official documentation for a more details), like this:

$messageQueryParams = array (
     "\$expand" => "attachments",
    //another params are omitted for clarity
);

Then attachments collection could be iterated like this:

 foreach($messages as $msg) {
    foreach($msg->getAttachments() as $attachment) {
        //...
    }
 }
