add folder to folder using google drive API - google-drive-api

Question

The script below is creating folders within a parent folder using
"google drive API". It works perfectly however, after a while (20 folders or so) it is not working anymore.
No error message just no more folder creation within the parent folder.
It goes somewhere else!
To enable that creation a "service account" was created and parent folder is share between "personal google account" and "service account"
Can someone provide help please?
php function send_google_drive($id,$fileno,$filename1,$filename2){
global $wpdb;

$client = getClient();
$service = new Google_Service_Drive($client);
if(!empty($filename1)){
$results = $service->files->listFiles();
foreach ($results->getFiles() as $item) {
if ($item['name'] == 'ENEMAT CRM FILES') {
$folderId = $item['id'];
break;
}
}
$parentid = $folderId;
$childid = "";

$childid = $item['id'];
break;

'name' => $fileno,

The reason there is no error message is because your code has no error handling! If GDrive fails to do something, it returns an error code and message to explain why. Your code should be catching that error and displaying it.
My guess is that you are hitting a rate limit. To see if this is the cause or not, add a 2 second delay between each folder creation. If it no runs correctly, you know that rate limiting is your problem.
