CI4 - > MySQLI Database -> query return result object even if error

Note I am in production mode thus the DBDebug = false then , thus in theory it should return false based on the logic in mysqli driver

PHP Code:

try
 {
return $this->connID->query($this->prepQuery($sql));
}
catch (\mysqli_sql_exception $e)
{
log_message('error', $e);
if ($this->DBDebug)
{
throw $e;
}
}
return false;
