Unable To Use @shopify/post-purchase-ui-react

[eni9889]

I am trying to use this package for developing upsell extensions: @shopify/post-purchase-ui-react

But I am getting the error I posted here Shopify/post-purchase-ui#16

I've made a sample repo here. You can reproduce the issue by running yarn dev at https://github.com/eni9889/shopify-frontend-template-react
