About an hour ago, our app’s GraphQL query suddenly started returning empty data (example below). This is a valid barcode for the merchant. Please help!

{
    productVariants(first: 100, query:"barcode:654287000026") {
        edges {
            node {
                product{
                    id
                    }                 
            }
        }
    }
}

Nevermind, this appears to be related to this Shopify issue .
