Connect from a Tryton instance to another one with XML-RPC

[Tatiana Quizhpe]

Hi.
I have a Tryton instance is going to be to used as XML-RPC server.

I have been trying to connect from another instance of Tryton like
is indicated in these examples [1] [2]. The method in where I call to
connect XML-RPC is in a button of my module but I get this error [2]
when click first time and this one [3] when I click second time in the
same button. Seems like is not possible to execute the method
with XML-RPC.

Anyone could to connect from one instance to another Tryton instance
with XML-RPC?

Any help would be very appreciated.

Thanks in advanced.

RegaGreetings

This is clearly that you are connecting to a database which is not up to
date with the trytond server version. Or the opposite the trytond server
version is older than the database.
The module table was renamed in 3.8
