After printing connection not closed and started receiving respnose again.

[Mayank Chauhan]

Hello support team,

I have updated my QZ code with latest version, but now i am facing the issue that is after receipt is printed successfully connection not closing and started receiving response. Before establishing the connection it gives me JavaScript error i.e.

TypeError: _qz.websocket.connection.sendData is not a function

Stack trace:
