How to markup (using JSON-LD) a Service to show price within a LocalBusiness in Schema.org? - schema.org

Question

When I test this code in validator, I am getting WARNING for the property price and the property priceCurrency. How do I fix this?
Thank you.
The property price is not recognized by the schema (e.g. schema.org) for an object of type Service.

Answer 1

In the markup, properties price and priceCurrency are located/belong to the Service object/type, which does not contain such properties. Those properties belong to the Offer, so they should be moved accordingly.
So just move them one level up, outside of the Service, so that they belong to the Offer object/type:
