An error occured while communicating to the server. JTable + ORM

[belenmolina1]

Hello! I have the following situation:
My idea is to be able to take data from a table, display it in the front end with JTable.
What I need is to be able to make the connection using ORM, that is Doctrine.
When I make the query to the table, it brings me the data, it prints them JSON, but it does not insert them in the table and it emits the message "Error
An error occured while communicating to the server."

Could you give me a hand?

Controller

JTable

Model

Front

Correct your code in function tableform() function

Correct
$jTableResult['Records'] = $contact->findAll();

You don't need
$data['contact'] = $contact->findAll();
