How to update a subscription product with a selected variant using graphQL?

[wpplumber]

Welcome,

The following code some product worked and others not, any reference for this operation?

mutation replaceSubscriptionProduct($id: String, $productId: ID,
  $variantId: ID,
  $qty: Int, $interval: String, $intervalCount: Int) {
  updateSubscription(
    id: $id
    input: {
      productId: $productId
      # items: { productId: $productId, quantity: $qty }
     quantity: $qty
      # options: {
      #   value:"Red"
      #   name: "Colour"
      # }
     variantId: $variantId
      billingSchedule: {
        interval: $interval
        intervalCount: $intervalCount
      }
    }
  ) {
    product {
      name
      id
      price
    }
    quantity
    trial
    grandTotal
  }
}

What do you mean by "some product worked and others not"?

Now it gives the same error as I had before.

Should I switch to swell-node? do you have an example using swell-node to achieve the same goal?

The product on the error has no relation with the current subscription of this operation, not on the plan nor on the invoice items!

Do you mean that this error is thrown only if the quantity is passed?

[logeshswell]

You need not switch to swell-node to update the quantity of subscription product. It should be done via graphQL or swell-js as well.

By reviewing the error message properly I found the issue with option, after setting it to null it works.
