Graphql functionality missing documentation

[adotterer]

Our client needs a custom widget that they are able to choose their own products and I'm trying to get the product details via graphql. How do I pass in the users selected productIds as queryVariables? Right now my bandaid fix is with first: 50

I'm doing my best to copy this:
https://github.com/bigcommerce/widget-builder/tree/master/src/services/__fixtures__

Code below:

Graphql:

query ProductList($productIds: [Int!]) {
  site {
    products(first: 50, entityIds: $productIds) {
      edges {
        node {
          entityId
          plainTextDescription
          name
          entityId
          addToCartUrl
          addToWishlistUrl
          path
          sku
          prices {
            price {
              currencyCode
              value
            }
            priceRange {
              min {
                value
                currencyCode
              }
              max {
                value
              	currencyCode
              }
            }
          }
          reviewSummary {
            summationOfRatings
            numberOfReviews
          }
          defaultImage {
            url(width: 1500, height: 1500)
          }
          customFields(names: ["New"]) {
            edges {
              node {
                value
              }
            }
          }
          productOptions(first: 5) {
            edges {
              node {
                __typename
                ... on MultipleChoiceOption {
                  values {
                    edges {
                      node {
                        entityId
                        label
                        isDefault
                      }
                    }
                  }
                }
                entityId
                displayName
              }
            }
          }
        }
      }

I have a feeling this is a bug. I could not get this working either.

Just like you, I created a minimum reproducible example
However, all I did was copy the __fixtures__ example without editing it. I could select products, but the products would not be queried.

Did you find any fix?
