Hello, I too am experiencing this issue. We are using Version 3.2.4 of the WP Shopify plugin.
Issue description: If our products in shopify do not have product variants, their product detail pages in our WP site properly display with no errors. However, if we add variants to our products, the product detail page in our WP site do not display properly:
1) there is an error related to react.js
Uh oh something went wrong. Please reload the page and try again. Minified React error #152; visit https://reactjs.org/docs/error-decoder.html?invariant=152&args%5B%5D=ln for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
2) The page does not display the quantity input, product variants or add to cart button.
Please let me know what further information I can provide that may assist in resolving this issue ??
