Error in export invoice

[David]

I'm using OCB branch for server and addons, and te latest magentoerpconnect connector whih respective dependencies (e-commerce, openobject-extension...)

I'm getting this error when I try to export the invoice to magento:

If you revert this commit, export invoices are ok, but without the improvement:
