Google analytics API sometimes return empty results

When using Google Analytics API (PHP Client library - as server to server service) many times it returns empty result set. My code look like this:

public function getLeadDetails($view, $gauid, $lead_id,$refresh_token,$dates = [])
{
    Log::info("*****************GA Service - GAUID: ".$gauid." **********************************");
    $options['dimensions'] = implode(',',config('analytics.dimensions'));
    $options['filters'] = "ga:eventAction==".$gauid;
    $metrics = "ga:users";
    $view = "ga:".$view;
    $yesterday = date('Y-m-d',strtotime('yesterday'));
    $tomorrow = date("Y-m-d",strtotime('tomorrow'));
    if(count($dates)){
        $yesterday = $dates['yesterday'];
        $tomorrow = $dates['tomorrow'];
    }
    Log::info('GA_Service@getLeadDetails(), Request Params: ?ids='.$view.'&start-date='.$yesterday.'&end-date='.$tomorrow.'&metrics='.$metrics.'&dimensions='.$options['dimensions'].'&filters='.$options['filters']);
    try{
        $this->client->setAccessType('offline');
        $this->client->setAccessToken($refresh_token);
        $this->client->setClientId(config('analytics.client_id'));
        $this->client->setScopes([
            \Google_Service_Analytics::ANALYTICS,
            \Google_Service_Analytics::ANALYTICS_EDIT,
        ]);
        $analytics = new \Google_Service_Analytics($this->client);
        $data = $analytics->data_ga->get($view,$yesterday,$tomorrow,$metrics,$options);
        if($data['totalResults'] && $data['totalResults'] > 0){
            Log::info('Inside GA_Service@getLeadDetails has totalResults');
            $rtn = [];
            $i = 0;
            foreach ($data['rows'] as $row) {
                $rtn['uacid'] = $gauid;
                $rtn['user_type'] = $row[0];
                $rtn['device_category'] = $row[1];
                $rtn['source'] = $row[2];
                $rtn['medium'] = $row[3];
                $rtn['campaign'] = $row[4];
                $rtn['ad_group'] = $row[5];
                $rtn['path'] = $row[6];
                $i++;
            }
            Log::info('Inside GA_Service@getLeadDetails lead '.$lead_id.' should be update');
            return $this->insertLeadDetails($rtn , $lead_id);
        }
        Log::info('GA_Service::getLeadDetails() returned empty results for lead: '.$lead_id);
        if(!count($dates)){
            $this->throwException('empty results for lead: '.$lead_id.' in GA_Service::getLeadDetails()',275);
            return false;
        }
        return 'empty results for lead: '.$lead_id.' in GA_Service::getLeadDetails()';
    }catch (\Google_Service_Exception $e){
        Log::info('Google service exception from GA_Service::getLeadDetails() - '. $e->getErrors()[0]['message']);
        $this->throwException($e->getErrors()[0]['message'], 335);
    }
    return false;
}

this function fire again every 5 minutes if the result was empty (5 times) and still misses some results.

any idea why and how to resolve it?
