product is not published for this customer error

[sppzglou]

my method is that:

val input = Storefront.CheckoutCreateInput() .setLineItemsInput( Input.value( listOf( Storefront.CheckoutLineItemInput(1, ID(graphQlId)) ) ) )

val query = Storefront.mutation { mutationQuery -> mutationQuery.checkoutCreate(input) { createPayloadQuery -> createPayloadQuery.checkout { checkoutQuery -> checkoutQuery.webUrl() }.checkoutUserErrors { userErrorQuery -> userErrorQuery.field().message() } } }

    graph.mutateGraph(query).enqueue { result ->
        if (result is GraphCallResult.Success) {
            val errors = result.response.errors
            val userErrors =
                result.response.data?.checkoutCreate?.checkoutUserErrors?.map { it.message }
            if (errors.isNotEmpty()) {
                emit(null, Exception(errors.first().message()))
            } else if (userErrors?.isNotEmpty() == true) {
                emit(null, Exception(userErrors.first()))
            } else {
                emit(result.response.data?.checkoutCreate?.checkout?.webUrl, null)
            }
        } else {
            emit(null, Exception((result as GraphCallResult.Failure).error.message))
        }
    }

on result.response.data?.checkoutCreate?.checkoutUserErrors I received this error "Variant the product is not published for this customer." on the same product/variant on web shopify site the checkout works without any error.
