variantForOptions always return undefined

[lezan]

I was testing the variantForOptions when I find out it is always undefined so this line

gatsby-starter-shopify/src/pages/products/{ShopifyProduct.productType}/{ShopifyProduct.handle}.jsx

Line 48 in 66d9909

client.product.helpers.variantForOptions(product, variant) || variant

always assign the second part (variant),

Checking Shopify documentation (here)[https://shopify.github.io/js-buy-sdk/product-helpers.js.html#line6] variant it is not what variantForOptions expect as the second argument but more an object like that

{
  size: "Small",
  color: "Red"
}

So maybe something like that can work and fix the issue

const productVariant = client?.product?.helpers?.variantForOptions(shopify, {
  [variant?.selectedOptions[0]?.name]: variant?.selectedOptions[0]?.value,
  [variant?.selectedOptions[1]?.name]: variant?.selectedOptions[1]?.value,
}) || variant;

If you wanna try it yourself just fork this repo and print the helpers with a console.
