TypeError: Cannot read property '1' of undefined

[ns16]

If when I create an object of class Invoice I pass a non-existent template then I get the following error:

/home/ns16/projects/viscur/license/invoice_server/node_modules/nodeice/lib/index.js:266
                callback(err, data[1], data[0]);
                                  ^
