• Lunar version: 1.0.0-beta3
• Laravel Version: 10.48.22
• PHP Version: 8.3.9
• Database Driver & Version: Mysql

Expected Behaviour:

I should be able to fill in product variant attribute data event though product has only one product variant (e.g. it has no options)

Actual Behaviour:

I am not able to fill in any product variant attributes.

Steps To Reproduce:

1. Assign some custom attributes to product variant.
2. Create a product and you won't be able to fill in any custom attribute_data on product_variant.

On lunar 0.8 it was possible to fill in this data, not we can't. Solution might be to create same attributes for the product too, but it create additional code complexity as you must check two places for attributes in a product and in a product variant.
