Wordpress in debug mode

Notice: Undefined index: filterByFormula in /Users/gobot/wordpress_air/wp-content/plugins/airpress/lib/chetmac/AirpressQuery.php on line 169

Code line is:
if ( preg_match_all($pattern, $params[“filterByFormula”],$matches) ){

My executing code using default Airtable table:
$query = new AirpressQuery();
$query->setConfig(“Artists_DB”);
$query->sort(“Name”, “asc”);
$query->table(“Collections”);
$data = new AirpressCollection($query);
