Python API add Product Variants fails

I am currently coding an Application in Python that should add Variants to Products on specific criteria using the Python Shopify API. I am always running into this Error:
"Failed to create variant for product 8463505031436: ['Option values provided for 1 unknown option(s)']"

I was unable to add new Variants to a specific Product with this code:



            # Ensure the necessary options are defined at the product level
            product.options = [
                    shopify.Option({'name': 'Size', 'values': ['Junior', 'Medium', 'Large']}),
                    shopify.Option({'name': 'Color', 'values': ['Lime', 'Orange']})
            ]
            # Save product with options
            product.save()

            # Create new variant object with associated product_id and option values
            new_variant = shopify.Variant({'product_id': product.id, 'option1': 'Junior', 'option2': 'Lime', 'price': '29.99'})
 
            success = new_variant.save()


If somebody could assist me here I would be very grateful.

Hey @tomarcoluh1 

 

You have reached the German community here but we can chat in English too, that's no problem!

 

Just off the bat, there could be a few reasons why this error might be occurring:

  1. API Latency: It might be possible that you're trying to create the variant immediately after saving the product, and due to some latency, the updated product options haven't propagated through the system yet. It might be worth adding a slight delay or checking to confirm the product options have updated before creating the variant (see the revised Python example below).

  2. Option Values Mismatch: Ensure that the values you are using in the variant match exactly with the values you've defined in the product options (e.g. case-sensitive).

  3. Existing Product Options: If the product already had some options set before your code runs, there could be conflicts. You might want to retrieve and check the product's current options first before overriding them.

Perhaps try this which includes a delay and some checking:

import time

# Ensure the necessary options are defined at the product level
product.options = [
    shopify.Option({'name': 'Size', 'values': ['Junior', 'Medium', 'Large']}),
    shopify.Option({'name': 'Color', 'values': ['Lime', 'Orange']})
]
# Save product with options
product.save()

# Wait for a short period to account for any potential API latency
time.sleep(5)

# Reload the product to ensure changes have propagated
product.reload()

# Check if the options are updated
if any(opt.name == 'Size' for opt in product.options) and any(opt.name == 'Color' for opt in product.options):
    # Create new variant object with associated product_id and option values
    new_variant = shopify.Variant({'product_id': product.id, 'option1': 'Junior', 'option2': 'Lime', 'price': '29.99'})
    success = new_variant.save()
else:
    print("Product options not updated yet!")

Hey Gabe,
thanks for suggesting these code changes but unfortunately the errors are still occurring. I completely changed the code to your suggestion above and now getting the print error "

Product options not updated yet!" Do you have any other possible solutions for that Problem?

Thanks for your great assistance!
