Whenever I use [with database.php LIBRARY pdo usage from mysql i think] the below I got above error? What must use commit/cancel with database.php library?

mycode.php
try {
$database = new Database();

$database->beginTransaction();
.………….
…………..
$database->endTransaction();
} catch (PDOException $e) {
$database->cancelTransaction();
//echo "Something went wrong: " . $e->getMessage();
} catch (Exception $e) {
$database->cancelTransaction();
//echo "Something went wrong: " . $e->getMessage();
}

database.php
public function cancelTransaction(){
return $this->dbh->rollBack(); // line 108
}
