403 error when making graphql XHR request to Shopify

I’m getting an error “Cannot read properties of undefined” from the src/api/operations-builder.ts (98:25) file from the nextjs-shopify repo. The cause looks like it’s because of an XHR request to https://my-store.myshopify.com/api/2020-07/graphql (“my-store” is replaced with a fake name here).

This happens when I try to add a Product Grid component to the page. The Product List shows up just fine in the Builder editor, but it seems to have a connection problem in the app shown in the editor once the Product Grid component has been added to the page. Here’s the request header copied from the Chrome console…

@bruceultra We recently made some changes to our nextjs-shopify repo that might help clear this up. You can see an outline of the changes here: What happened to my Shopify <> Builder sync requests? · Issue #25 · BuilderIO/nextjs-shopify · GitHub

Could you pull from master and see if that resolves your issue? If you continue to see the issue, please send us a link to your space or your API key (here or in a DM is fine) and I can investigate further
