Product variants error

[dripdevelopment]

Why am I getting always only the last variant of a product, even if I specify to get more than 1 (e.g. first: 3)?

I've tried a couple of things, the first was directly fetching variants by searching variants with the same product_id, and I've also tried fetching all the variants in a product query (e.g. query{products(first: 10){edges{ node{ variants(first:10){edges{node{}}}}}}} )

Hey @dripdevelopment,

I think you should provide more details about your issue.

I tried this query and everything works fine:

query {
  products(first: 10) {
    edges {
      node {
        title
        variants(first: 10) {
          edges {
            node {
              id
              title
            }
          }
        }
      }
    }
  }
}

Thank you for your response. I have already contacted support regarding this issue but have not yet received a reply. The problem I'm having is that, even if certain product has more than 1 variant, I always get the latest one and I can't find a way to fetch all the variants from specific product.
e.g. I only get 1 variant (the one with the position #2)

query {
  productVariants(first: 10, query: "product_id:9670723305788") {
    edges {
      node {
        id
        position
        price
        sku
        inventoryQuantity
        inventoryPolicy
        image{
            url
        }
        createdAt
        updatedAt
      }
    }
  }
}

Hey @dripdevelopment, I think you are doing something wrong here, if you look at the documentation of the ProductVariant Object you see you can get a variant from the variant id or you can get a variants list that is not something related to a single product. 
https://shopify.dev/docs/api/admin-graphql/2024-07/objects/ProductVariant#queries

I'm curious, can you please provide me the documentation about this filter you are using? product_id:9670723305788

However, what you should do instead is something like this:

query getProductWithVariants($productId: ID!) {
  product(id: $productId) {
    id
    variants(first: 100) {
      edges {
        node {
          id
          position
          price
          sku
          inventoryQuantity
          inventoryPolicy
          image {
            url
          }
          createdAt
          updatedAt
        }
      }
    }
  }
}

Thanks for the provided query, but I'm still getting just 1 variant. I'd expect to get all the variants from a specific product if I provide the product_id (as specified in the docs), like it happens in REST Admin

Hey @dripdevelopment,

thank you for providing the documentation, I tried it and that actually works. I specified an id of a product with 6 variants and i got back 6 variants. 
If you try my query do you get more than one variant?

[dripdevelopment]

Good to know that you're getting more than 1 variant, perhaps it's an issue related to my account. I tried your query, but it only returns 1 variant where there should be 2 at least.
