Missing file in my email when doing resumable upload with gmail api - api

Question

I'd like to have some help because I'm a bit lost right now.
I'm trying to send attachment with my email through resumable upload. But when I check my email in my inbox, I don't see any file. So I've probably forgot something.
Here's my code. So if someone see something ^^
$send_data = 'From: <FROM_EMAIL>' . "\n";
$send_data = 'To: <TO_EMAIL>' . "\n";
$send_data = 'Subject: <SUBJECT>' . "\n";
$send_data = '' . "\n";
$send_data = '<MY MESSAGE>' . "\n";
$send_data= rtrim(strtr(base64_encode($send_data), '+/', '-_'), '=');
$msg = new \Google_Service_Gmail_Mesage();
$msg->setRaw($send_data);
$this->client->setDefer(true);
$request = $this->service->users_messages->send('me', $msg, array('uploadType' => 'resumable'));
$chunkSizeBytes = 1 * 1024 * 1024;
$media = new \Google_Http_MediaFileUpload(
$this->client,
$request,
'message/rfc822',
null,
true,
$chunkSizeBytes
);
$media->setFileSize(filesize(TEST_FILE));
$status = false;
$handle = fopen(TEST_FILE, "rb");
$i = 0;
while (!$status && !feof($handle)) {
$chunk = fread($handle, $chunkSizeBytes);
$status = $media->nextChunk($chunk);
}
$result = false;
if($status != false) {
$result = $status;
}
fclose($handle);
$this->client->setDefer(false);
Thanks

I don't know much about gmail api, but I feel like setRaw() will need you to compose the full email (include the attachment) instead just of "body".
