I'm using AppEngine under Windows for development. I've tried to create data in Datastore.
Unfortunately CGI/FastCGI will gone every time I call the demo script

I've found that this line is producing the issue.
$service_dataset->commit($dataset_id, $req, []);
After looking to the Datastore.php from this lib I've replaced return value by a simple return.
/**
* Commit a transaction, optionally creating, deleting or modifying some
* entities. (datasets.commit)
*
* @param string $datasetId Identifies the dataset.
* @param Google_CommitRequest $postBody
* @param array $optParams Optional parameters.
* @return Google_Service_Datastore_CommitResponse
*/
public function commit($datasetId, Google_Service_Datastore_CommitRequest $postBody, $optParams = array())
{
$params = array('datasetId' => $datasetId, 'postBody' => $postBody);
$params = array_merge($params, $optParams);
return;
return $this->call('commit', array($params), "Google_Service_Datastore_CommitResponse");
}
The issue was gone. As expected without data in the Google Datastore.
After deploying this to the cloud the script is working well. So I think it's only a local issue.
Is there anybody who have/has the same issue?
