Hi there,

I have an issue with productVariantCreate (GraphiQL version 2024-04), please see below for the mutation, variable and response.

Thank you,

The mutation:

mutation productVariantCreate ($input: ProductVariantInput!) {
productVariantCreate(input: $input) {
product {
id
}
productVariant {
id
barcode
sku
inventoryItem {
id
}
}
userErrors {
field
message
}
}
}

The variables:

{
“input”: {
“barcode”: “Super.0403M-1605N//000S.HDCL”,
“options”: [ “S” ],
“position”: 1,
“price”: “89.99”,

“taxable”: true,
“inventoryQuantities”: [

I know it is a single variant product. But before add variant I did add options, as below:

mutation:

mutation createOptions ($productId: ID!, $options: [OptionCreateInput!]!) { productOptionsCreate (productId: $productId, options: $options) { product { id variants (first:10) { nodes { id barcode sku inventoryItem { id } } } options { id name values position optionValues { id name hasVariants } } } userErrors { field message } } }

variable:

{“productId”:“gid://shopify/Product/7991957979306”,“options”:[{“name”:“Taille”,“values”:[{“name”:“S”},{“name”:“XS”},{“name”:“XL”}]}]}

Hey bro
sku deprecated you need to use inventoryItem.sku

and you can look up the docs here

It seems working if I remove the element below from the variable. But even though the variant was created, it still gave me an error like ‘S’ already exists. Of course ‘S’ exists and that’s what I want.

“measurement”: null,
