  • Have you provided a full/minimal spec to reproduce the issue?
  • Have you validated the input using an OpenAPI validator (example)?
  • Have you tested with the latest master to confirm the issue still exists?

Description

If a property is documented as an array of unique items the generator sets the property's type in the TypeScript file to a Set of the item type e.g. Set<string>. The problem is that Set is imported from a resource which does not exist.

import { Set } from './Set';

This line should not be generated.
