Reordering Product Option Values -> Various errors

[conorseed]

Hey :) Looking at reordering the values of a specific product option named "Delivery Option". There's over 1000 products and most have this as an option field, and they all need reordering so that "Rural Delivery" is last.

I can query the products and reorder the options just fine. However, I can't update the product. I've tried the below rest query:

$newProduct = array(
            "options" => $product['options']
    );
    $result = $shopify->Product($product['id'])->put($newProduct);

But this results in Request failed with HTTP Code 406.

I've also tried a graphql query to update as below:

$graphQL = <<<Query
    mutation updateProductOptions(\$input: ProductInput!) {
        productUpdate(input: \$input) {
            product {
              title, options{name, values}
            }
            userErrors {
              message
              field
            }
          }
      }
    Query;

    $variables = [
        "input" => [
            "id" => $product['id'],
            "options" => $product['options'],
        ]
    ];
    $result = $shopify->GraphQL->post($graphQL, null, null, $variables);

And this results in this error: Variable $input of type ProductInput! was provided invalid value for options.0 (Could not coerce value "{\"name\"=>\"Delivery Option\", \"values\"=>[\"Ground Floor CBD\", \"Residential & Suburban Commercial\", \"Above Ground Floor Delivery\", \"Rural Delivery\"]}" to String), options.1 (Could not coerce value "{\"name\"=>\"Colours\", \"values\"=>[\"Black PU Leather - KG_SWT_PU\", \"Navy Fabric - KG_SWT_N_ASS\", \"Black Fabric - KG_SWT_B_ASS\"]}" to String)

Can anyone see what's going on here?
