`BulkWrite error :: norepl` mongodb php BulkWrite - php

Question

I getting this is exception in my application, and don't understand why. This exception throw in for one collection, over collection not throw this exception, with processed insert(),update(), or delete()
/**
* insert to mongo db method
* #param $dataArray
* #param $collection
*/
static function insert($dataArray, $collection) {
$connect = Core_Model_Mongo::getConnect();
$write = new MongoDB\Driver\BulkWrite();
$writeConcern = new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY);
$write->insert($dataArray);
$connect->executeBulkWrite(
Config_Db::getConf()['mongodb']['db'].'.'.$collection,
$write,
$writeConcern
);
}
end get connect method
/**
* #return \MongoDB\Driver\Manager
*/
static function getConnect() {
if(!is_null(self::$_connect)) {
return self::$_connect;
}
self::$_connect = new \MongoDB\Driver\Manager(Config_Db::getConf()['mongodb']['connect']);
return self::$_connect;
}
data save in collection success full, and this exception not take insert(),update() and other methods. I temporary resolve this question by try catch block
try {
// my code
} catch(MongoDB\Driver\Exception\BulkWriteException $error) {
Core_App::log(var_export($error,true));
}
but this is resolve not correct because I need application without any exception,error,notice, and over log level error.
