Tutto funziona alla grande ma restituisce un errore

[zacca94]

function dbFetchEscapedArray($queryId, $not_parsed_columns = array()) {
    global $dbConnect;
    $result = $dbConnect->mysqli_fetch_array($queryId, MYSQLI_ASSOC);
    foreach ($result as $key => $value) {
        if (!in_array($key, $not_parsed_columns)) {
           $result[$key] = UTF8_htmlSpecialChars($value);
        }
    }
    
    return $result;
} 

Errore:
