[api-extractor] Internal Error: Unable to follow symbol for "Set"

[andreasbalzer]

Summary

microsoft-api-extractor throws 'Unable to follow symbol for "Set"' after I added a JavaScript Set to my code.

I added a Set to an exported type: export type SiteSetting = { licenses?: string[]; activeFlights: Set; };

Repro steps

I'm happy to provide PR details via email.

Expected result: no error message

Actual result: unning API Extractor Analysis will use the bundled TypeScript version 5.0.4 *** The target project appears to use TypeScript 5.3.3 which is newer than the bundled compiler engine; consider upgrading API Extractor. API Extractor failed with the following error: InternalError: Internal Error: Unable to follow symbol for "Set"
