Phalcon no exception message

i have the following table:

table_1
id int(11) PK NOT NULL
name VARCHAR(11)

Note; id is not auto_increment

When i tried to insert:

$this->db->begin();
try{
    $entry = new Table1();
    $entry->name = 'Juan';
    if(!$entry->save()){
        $this->db->rollback();
        echo $entry->getMessage(); //no error
    }
}catch(Exception $e){
    echo $e->getMessage(); //no error
    $this->db->rollback();
}catch(\Phalcon\Mvc\Model\Exception $x){
    echo $x->getMessage(); //no error
    $this->db->rollback();
}catch(\PDOException $r){
    echo $r->getMessage(); //no error
    $this->db->rollback();
}
$this->db->commit();

I expect an error because i didn't define id, id is not auto increment, however, php doesn't give me anything. Please help.

The entry was not inserted btw.

And you don't have anything in logs ? What just $entry->save return ? Also you should do print_r($entry->getMessages()) instead of $entry->getMessage() There are no basically method like getMessage() in Phalcon\Mvc\Model, there is getMessages() which returns array of messages.
