Cannot apply selling plan to variant

[Tiber]

I have created a subscription Group on a products variant, but when I try adding the item to the cart I am getting

status: 422, message: "Cart Error", description: "Cannot apply selling plan to variant"

mutation {
  sellingPlanGroupCreate(
    input: {
      name: "Monthly"
      merchantCode: "Monthly"
      options: ["Monthly"]
      position: 1
      sellingPlansToCreate: [
        {
          name: "Monthly"
          description: "Payments the first of the month"
          options: "Monthly Payments"
          position: 1
          billingPolicy: { recurring: { interval: MONTH, intervalCount: 1 ,maxCycles:8, anchors:{type:MONTHDAY,day:1}} }
          deliveryPolicy: { recurring: { interval: MONTH, intervalCount: 1 , anchors:{type:MONTHDAY,day:1}} }
				   
        }
      ]
    }
    resources: { productIds: [""], productVariantIds["gid://shopify/ProductVariant/4127279"] }
  ) {
    sellingPlanGroup {
      id
    }
    userErrors {
      field
      message
    }
  }
}

I was using SellingPlanGroup id not SellingPlan id

@Tiber  Can you explain where are you using the SellingPlanGroup id instead of the SellingPlan id?

Hey @Lokesh_Saini 

 It was for adding an item with a subscription through JavaScript
