Alternative for incorrect OAuth swagger specification

The URL https://api.hubspot.com/api-catalog-public/v1/apis/oauth/v1 is one of the default swagger specifications.

However, it’s contents are not a valid swagger / OpenAPI specification. For instance, the required “title” is missing.

All these specifications are automatically converted into a HubSpot data model on our UniversalSQL-engine, but the queries on OAuth entities are not available due to the incorrect format.

Is there an alternative available which contains valid OpenAPI specification for Oauth topic?
