Attribute field name mismatch in Get Product Details and Get Product Variations

@pujithamutyala Thank you for reporting this mismatch. Will review what needs adjusting to fix this and have a patch out asap.

Thank you. Can you please update this topic once this is fixed?

Yes of course.

@pujithamutyala After reviewing the issue, I find it is related to how WordPress sanitize the slugs. The character e and is replaced with a d

I don’t see a way to prevent this.

But if Woocommerce sanitizes the slugs, it should be the same in both product endpoint and product variations endpoint. Why is there a difference?

In the products endpoint, the attribute name is “attribute_malae?” which is not correct.

GET https://stokkur.wpcomstaging.com/wp-json/cocart/v1/products/406

Response Snippet:

"attributes": {
        "attribute_malae?": {
            "id": 0,
            "name": "Malae?",
            "position": 0,
            "is_attribute_visible": true,
            "used_for_variation": true,
            "options": [
                "Nei - Baunir",
                "Já - Filter",
                "Já - Mokkakanna",
                "Já - Pressukanna",
                "Já - Aeropress",
                "Já - Espresso"
            ]
        }

I don’t know how you have it returning like it does. I have created a variable product with the same attributes and mine return sanitized and match for both endpoints.

Maybe there is something that you have done differently in the backend that I missed or you have another plugin that filters the attributes but the data fetched is the same.

I have compared the data returning on the products page vs the REST API and they match.

Any other information you can share that might help would investigate further.
