VAPI's OpenAPI schema (
https://api.vapi.ai/api-json) includes lots of component with properties that use enum values as discriminators (e.g. most schemas with a "model" or "provider" property). However, some of these component schemas do not include the discriminator field in the "required" field. As a result, using generator tools to create models from your OpenAPI spec generates invalid models. Can you update the OpenAPI schema to correctly mark all discriminator fields as required?
