Google 日历 API(超出日历使用限制)

I am using Google Calendar Api in my php project, and I every day get "Calendar usage limits exceeded" message when I doing insert query, but delete and list methods work fine․ It is my insert function. who can help me?

function insertEvent($start, $end, $cId, $namePhoneClient,$myEmail,$trainerMail){

$client = getClient();
$service = new Google_Service_Calendar($client);
$event = new Google_Service_Calendar_Event(array(
    'summary' => $namePhoneClient,
    'start' => array(
      'dateTime' => $start,
      'timeZone' => 'Europe/Moscow',
    ),
    'end' => array(
      'dateTime' => $end,
      'timeZone' => 'Europe/Moscow',
    ),
    'recurrence' => array(
      'RRULE:FREQ=DAILY;COUNT=1'
    ),
    'attendees' => array(
      array('email' => $myEmail),
      array('email' => $trainerMail),
    ),
));

$calendarId = $cId;
$event_inserted = $service->events->insert($calendarId, $event);

return $event_inserted; 
}
