Preconditions:

• Use default ibexa.yaml config
• Added Attribute group
• Added Attribute e.g. selection based on Attribute group
• Added Product type with defined Attribute group and Attribute selection and selected an option 'Used for product variants'

Steps to reproduce

1. Log in to backoffice.
2. Go to Product catalog / Products.
3. Add a new product based on Product type from preconditions.
4. Switch tab to variants on created product.
5. Start generating product variants.

Actual result:

Generating variants on default ibexa.yaml config causing an 500 internal server error

An exception has been thrown during the rendering of a template ("Cannot resolve currency. Missing configuration under the ibexa.system.[your_siteaccess].product_catalog.currencies key"). 

Expected result:

The product variants are generated without any issues.
