ShopifyCart.instance addLineItemsToCart throws an exception #95

I am getting an error adding line items to a cart. The error is : 

addLineItemToCart Error: type 'List<dynamic>' is not a subtype of type 'List<CartDiscountAllocation?>?' stack: #0      new Line.fromGraphJson (package:shopify_flutter/models/src/cart/lines/line/line.dart:44:11)

I/flutter ( 8441): #0      _CartTabState.addLineItemToCart (package:example/screens/cart_tab.dart:113:46)

This stack trace is from the example app included with the sdk (I added the stack trace on error), I tried my own implementation and got a similar error. I have tried going back to version 2.0.0 but see a similar error there. Not sure if this could be related to #94 ? Thanks for putting this package together, any insight is much appreciated.

EDIT: I am able to add line items to the cart using curl and a graphql query so I think the shopify storefront config I am using is ok.
