I'm a new user and would like to populate a book library. I selected the default book library, have a barcode field, downloaded the scanner and selected "field autocompletion." I had hoped by scanning the bar code, it would populate the other fields. What happens is an error, "Sorry product not found," and "Can't execute request to Google Shopping, response precondition failed." When I use the barcode scanner outside of Memento it readily identifies the book. Any suggestions?
