Expected Behavior

I expect that in the following code snippets, tsoa will properly resolve the imports & types, generating the correct openapi schema on output.

// types.ts
/**
 * Stringified UUIDv4.
 * See [RFC 4112](https://tools.ietf.org/html/rfc4122)
 * @pattern [0-9A-Fa-f]{8}-[0-9A-Fa-f]{4}-4[0-9A-Fa-f]{3}-[89ABab][0-9A-Fa-f]{3}-[0-9A-Fa-f]{12}
 * @format uuid
 */
export type UUID = string;

// thing.controller.ts
import type { UUID } from "types.ts";

@Route("/api/v1/user/")
export class UserController extends Controller {
  @Get("/")
  @Security("jwt")
  async getUsers(
    @Query("userIds") userIds: UUID[],
  ): Promise<NonSensitiveUser[]> {
    const users = await db
      .select(defaultUserSelection)
      .from(Users)
      .where(inArray(Users.id, userIds));

    return users;
  }
}

Current Behavior

Tsoa errors while attempting to build and generate swagger for this code.
