Shopify query using shopfy_api gem

[tamara_mcd]

I am trying to query inventory items at a specific location using the shopify_api gem. If I just put a location ID into the query it works but when trying to pass it as a variable, not so much... any help would be appreciated.

def query_using_location_ids
      client.parse <<-'GRAPHQL'
      {
        query inventoryItemsAtLocation($locationId: ID!) {
          inventoryItems(first:10){
            pageInfo{
              hasNextPage
              hasPreviousPage
            }
            edges{
              node{
                id
                legacyResourceId
                inventoryLevel(locationId: $locationId){
                  id
                  available
                  incoming
                  item{
                    id
                    legacyResourceId
                    sku
                    variant{
                      id
                      legacyResourceId
                      price
                      product{
                        description
                      }
                    }
                    unitCost{
                      amount
                      currencyCode
                    }
                  }
                }
              }
            }
          }
        }
      }
      GRAPHQL
    end

   def client
      @Client ||= ShopifyAPI::GraphQL.client
    end

client.query(query_using_location_ids, variables: {locationId: id}).original_hash["data"]["inventoryItems"]
id passed is the global ID of the location
