Description

If a property is marked as deprecated in openapi spec, it has no effect on the generated typescript sdk. The generate model has no deprecation marker on the deprecated property. The generate model looks like:

export interface GameDto { 
    nationalLeague: boolean;
    results: boolean;
    id: number;
}
