Importing a solution according software factory

I want to import a solution according to the documentation Software Factory
https://wiki.servoy.com/display/Serv7/B … re+Factory

I’m using the sample solution that is available in https://svn.servoy.com/examples/Softwar … verUpdater

When I run the solution, after adjusting the parameters, I have the following error

var rtn = poster.executeRequest (‘admin’, ‘XXX’); // 200 is ok httpCode
rtn.getStatusCode httpCode = var ();

But rtn variable always returns null

That may be happening?

I’m using Servoy 7.4.2. build 2033 and server Linux Centos 6.5
